version 0.1.0 |
6/97. This is the first numbered version.
- Thermal color map.
-
Bug fix: disconnected nodes weren't reconnected when
empty elements were replaced with non-empty elements.
|
version 0.1.1 |
6/4/97
-
Replace spaces in group names with underscores. Spaces
couldn't be parsed properly.
|
version 0.1.2 |
6/5/97
- Installed new menu routines. Changes in variables set in
scripts are now reflected in GUI menus.
|
version 0.1.3 |
6/97
- Moved preconditioner setting from separate menu to
enumerated variable with pull down menu.
- Got rid of conversion from StressStrain to
MV_Vector_double, which was confusing the 64 bit compiler.
|
version 0.1.4 |
6/5/97
- Moved statistics type to enumerated variable w/ pull
down menu.
|
version 0.1.5 |
6/6/97
-
Print all settable variables in binary goof
file. Print empty strings with quotation marks so that
they don't look like missing arguments when reading
the goof file.
|
version 0.1.6 |
6/10/97
- Print all settable variables in ascii goof file too.
|
version 0.2 |
Identical to version 0.1.6, put on the web site.
|
version 0.2.1 |
6/24/97
- Increased blocksize for groups so they can be
allocated faster.
|
version 0.2.2 |
7/1/97
-
Fixed bug in arithmetic with stress & strain
classes that was causing "Incompatible vector length"
errors.
|
version 0.3 |
7/2/97
-
Reorganized "distort" menu. This breaks (slightly)
existing goof files. The distortions stored in them
won't be read correctly. But it turns out that if the
files were written by oof, they weren't written
correctly since version 0.1.5 anyway.
|
version 0.3.1 |
7/7/97
-
Got rid of old "axis" output commands. Nobody used
them anyway, presumably.
|
version 0.3.2 |
7/9/97
-
Changed 11 to XX in menus, to avoid confusion. We're
told that 11 is the principle component, not the xx
component, of stress.
|
version 0.3.3 |
7/15/97
- Fixed bug wrt proliferation of disconnected nodes.
|
version 0.3.4 |
7/30/97
- "distort set reset_params" now works properly.
|
version 0.3.5 |
8/5/97
-
Clumsy bug fix. bc & distort commands read from
goof file are stored in cmdlist with "oof" prefix,
since that's the way they appear in the file. But then
they're written with another "oof" prefix, so the next
time they're read errors are generated. Clumsy fix is
to put a oof->oof loop in the root menu. The problem
with this is that the goof file keeps getting bigger
each time it's written.
|
version 0.3.6 |
8/6/97
-
fixed clumsiness in 0.3.5. Goof file still keeps
getting bigger, because commands are repeated, but
oof->oof loop isn't needed.
-
Plot principal values of stress & strain.
-
Got rid of "suffix" variable.
|
version 0.4.0 |
8/21/97
- 8-bit graphics, new ScrollCanvas
|
version 0.4.1 |
8/22/97
-
pixmap backing for color bar, so that it draws faster,
and draws correctly in 8-bit mode. Not working
yet.
|
version 0.4.2 |
9/5/97
-
don't include "principal" and "shear" in element info
eigenvalues. They were nonsense.
|
version 0.4.3 |
9/9/97
-
change colors in colorbar by clicking on them. Left
mouse changes color, right mouse prints color info,
middle mouse reverts to default color.
|
version 0.5 |
9/16/97
-
Nothing new. Changed number to have a round number to
put on the web.
|
version 0.5.1 |
9/16/97
-
Can turn wallpaper on and off. Can't change color,
though.
|
version 0.5.2 |
9/23/97
- "Save" button now works in graphics windows.
|
version 0.5.3 |
9/25/97
- Removed "bc force" command. Forces can be applied
to all nodes.
- New "distort clear" menu to clear incremental and
absolute distortions from node groups.
-
|
version 0.5.4 |
10/30/97
-
Got rid of "-t" command line option, and disabled
graphics menu when "-g" isn't specified.
-
Fancy text start-up screen.
|
version 0.5.5 |
10/97 -- 11/97
- Fixed bugs wrt saving macros and defining macros
that set variables.
-
Use XForms code for handling command line
arguments. -l <logfile> added. -f <cmdfilelist>
now requires comma delimited list of files, without
spaces. -f can't be specified multiple times anymore.
-
-g is no longer needed. Use -t to
use the text interface.
|
version 0.5.6 |
11/19/97
- Mouse clicks are recorded in log files and can
be played back. Colorbar editing temporarily disabled.
- Record window size changes in log file.
- Catch "close" events from window manager, and
ignore them, mostly.
- Ask to save log file when quitting.
|
version 0.5.7 |
11/20/97
- Fixed bug in colorbar editing. Middle mouse made
colors revert to slightly wrong colors.
- Reinstated color bar editing. Mouse clicks on
the colorbar are now recorded in the log file.
- X cursors are defined only once and freed at the
end, instead of being defined in each drawer.
|
version 0.5.8 |
1/98
- Inserted missing space in ascii output for
hexagonal elements.
- No longer require element indices to be in order
in ascii goof files.
- "Empty Elements" button in Attributes dashboard
now works. Had been broken in 0.5.6, probably.
|
version 0.6.0 |
2/3/98
- Installed XForms version 0.88
- Changed -f option to -file, since XForms 0.88 uses -f.
-
Fixed bug. Coordinates Dashboard would sometimes not
show limits of visible region.
-
Got rid of single character command line
options. XForms processes its own options before the
application's options, so single character options can
be mistaken for abbreviated XForms options.
- Cleaned up memory leaks in dashboards.
-
Use fl_share_canvas_colormap. Should allow windows to
be closed w/out crashing on 8 bit displays.
|
version 0.6.1 |
3/17/98
- Workaround for bugs caused by new XForms library.
- Fixed bug with spaces in EulerAngle input.
- Allowed E format for floating point inputs.
|
version 0.6.2 |
3/18/98
-
More workarounds for bugs caused by new XForms
library. Color dashboards with fullscale turned off
would crash when switching or closing drawers.
|
version 0.6.3 |
3/26/98
- Upgraded to XForms version 0.88.1 from 0.88.
|
version 0.6.4 |
3/27/98
- Weight statistical output by element area.
|
version 0.6.5 |
4/17/98
|
version 0.6.6 |
5/4/98
- Disable "debug Xdebug" in text mode.
|
version 0.6.7 |
5/15/98
- Don't use fast malloc library -- it uses too much
space!
|
version 0.6.8 |
5/26/98
- Avoid resizing arrays, improved connectivity detection.
- Add Nelements and Nnodes lines to the goof files.
|
version 0.6.9 |
5/98 -- 6/98
- Tie degrees of freedom together, so that all the
nodes on an edge can move in unison. (Not working yet...)
- Bug fix: internally generated grids put the wrong
node in the topright node group unless nx == ny.
- Graphics output for shear stress & strain.
|
version 0.7.0 |
6/98
-
Slaved nodes finally working, I think.
-
Zimmer & Griffith elements revert to unmutated
state properly when reset.
-
Changed single/double click behavior in menus. Single
clicks now bring up function windows, and double
clicks execute functions immediately. This is the safe
way to do it if you're running over a slow connection
and the double clicks aren't getting through in
time. You can recover the old behavior by starting
with the -singleclickfns option.
|
version 0.7.1 |
7/98
- "Home" key on keyboard brings the root menu to the
front.
- "select node number" command
- "select element number" command
|
version 0.7.2 |
7/30/98
- Added "griffith_element2" as a stopgap
measure. It's still not quite correct.
|
version 0.7.3 |
8/98
- Didn't succeed in fixing "output energy" command
to account for stress free strains. "output force" is still
broken.
- "log save" command to save log file now, without
quitting.
- Fixed InfoDashboard "node type" button.
|
version 0.7.4 |
8/98
- Fixed "output force" command (sign error was
causing bad output when deltaT was non-zero).
- Fixed "output force" -- possible wrong output if
force measured after nodes were freed.
|
version 0.7.5 |
9/15/98
- Mutated elements are stored in goof files correctly.
|
|
version 1.0 |
9/15/98
- Just renamed version 0.7.5
|
version 1.0.1 |
9/29/98
- Made the question mark cursor like the one in
PPM2OOF, with the hotspot below the dot.
|
version 1.0.2 |
10/30/98
- Fixed bug in "output force". Program would crash if system
hadn't been equilibrated.
|
version 1.0.3 |
11/4/98
|
version 1.0.4 |
1/7/99
-
Use new ostream class for output. Colored text in
message window.
-
New commands "output tee ..."
|
version 1.0.5 |
1/27/99
-
New button in Element Info dashboard, for
printing element index.
-
Fixed bug in which applied forces weren't being
applied! Bug existed since version 1.0.3.
|
version 1.0.6 |
3/2/99
-
Installed kludge that lets programs compiled under
IRIX 6.5 run under IRIX 6.2.
|
version 1.0.7 |
3/99 -- 4/99
-
Fixed bug in unmutating elements. Zimmer elements
didn't revert to original orientation. Fixing the bug
invalidates old goof files that store mutated
elements, though.
-
Mutate and equilibrate commands can be interrupted
with "STOP" button.
- Fixed crash when reading ascii
goof file after "init uniform ..."
-
Avoid double redraw after reading goof file.
-
Correct placement of initial image after reading ascii
goof file.
-
New more robust vec.C.
|
version 1.0.8 |
5/99
-
Fixed a bug in which the shear stresses weren't
being reported properly for some elements.
-
Fixed a bug in which forces weren't being reported
correctly for enslaved nodes. The sign convention for
forces has also been changed -- a positive force on
the right edge now means that the system is being
pulled to the right. (The old convention was that
"output force" showed the force that the sample
exerted on the boundaries, rather than the force the
boundaries exerted on the sample.) Changed "applied
force" button in NodeInfo dashboard to "force".
-
Ported to Sun!
6/99
-
Clicking in the wrong spot on the dashboard selector
would bring up the main menu window. Fixed by moving a
hidden button.
-
When mutating elements, the principal stress is
computed in 3D, not just in the XY plane, in order to
determine the coordinate system in which the knockdown
is performed.
-
Fixed bug: Damage element applied knockdown2 to C_45 twice.
-
Restructured Element Info dashboard. All components of
stress and/or strain are printed when the "components"
button is lit, and all invariants are printed when the
"invariants" button is lit.
-
Fixed bug in which not all element info buttons were
recorded properly in the log file.
-
Strain outputs ("output strain" command, and graphics
windows) report the total strain, not the elastic
strain. The strain reported in previous versions was
the two-dimensional elastic strain used in plane
stress and plane strain calculations, which is not the
true elastic strain when using plane strain and
thermal expansion.
-
Fixed bug. The griffith2 element hadn't been
appearing in the menus, but the griffith menu options created
griffith2 elements. Binary files written by PPM2OOF were read
correctly. Binary files written by OOF created only griffith
elements. Ascii files written by OOF created only griffith2
elements.
-
"STOP" button now doesn't take up 25% of the CPU, uses
forked process.
-
comp_equil now stops if the equilibration step
fails to converge.
-
Fixed plane stress calculation. It no longer crashes
when out-of-plane moduli vanish.
(OK, it's more useful to list beta version numbers than
dates...)
1.0.8 beta 9
-
The STOP button works properly.
-
There are now drawers for the 3rd principal
and 3rd invariants of stress and strain.
-
The Element Info dashboard reports the
direction of the eigenvectors for each
eigenvalue, expressed as an Euler angle
rotation from the z axis.
-
The griffith2 element compares the surface energy to
(1-knockdown1) times the energy stored in the
direction of the principal stress, ie, the
amount of energy that would be released if the modulus
in the direction of the principal stress were reduced
by knockdown1. It's still not a real Griffith
criterion, but it's getting closer.
1.0.8 beta 10
-
Bugs were found and fixed in the computation of the
stress in plane-stress calculations.
-
The program no longer crashes when an out-of-plane
modulus is zero in plane-stress calculations.
1.0.8 beta 12
-
The "STOP" button was redone once again. It now
doesn't require a separate process, and still doesn't
take CPU time away from the ongoing computation.
-
The "plot out" command works, again (I think).
-
Output from "output tee" is line buffered, so that you
can view results before the file is complete.
1.0.8 beta 13
-
Removed garbage at the beginning of lines in files
written by the "Save" buton in the Message Window.
-
Graphics windows remember their settings when
switching between different views. For example,
if you manually set the range of displayed values in a
Stress XX window, that range will be retained if you
switch to Stress YY and back to XX.
-
The elements in the files written by commands in the
"output individual" menu are now sorted by element
index.
1.0.8 beta 14
-
Fixed a bug introduced in beta 13 when making graphics
windows remember their settings.
1.0.8 beta 15
-
Fixed a bug in the zimmer element that caused the
"reset" command to fail if the element had mutated
more than once.
1.0.8 beta 17
-
Added trigonalA, trigonalB, trigonalCrack, and zimmer2
elements.
-
Fixed a bug that put garbage in the log file when then
elementtype button was changed in he element info
dashboard.
1.0.8 beta 18
-
Unknown element types in the header of the binary
.goof file no longer cause an error unless they're
actually used in the mesh.
1.0.8 beta 19
-
Fixed a bug introduced in 1.0.8 beta 13 that was
preventing the graphics windows from updating properly
in some circumstances.
1.0.8 beta 20
-
Added tetragonal elements and kessler element. The
Kessler element implements a model of ferroelastic
switching from Hannes Kessler.
-
Worked around a bug (maybe a feature) in the GNU
iostream library that was breaking the
output/individual commands in the Linux versions of
OOF.
1.0.8 beta 21
-
Added Nelements and Nnodes data to the
output/grid/ascii file format. Their absence made
grids read from ascii files take up more memory than
they should have, but didn't otherwise affect the
program.
1.0.8 beta 22-24
-
Added an "enhancement" variable to the main menu for
enhancing the displayed displacements. Nodes are
drawn at their original position plus
enhancement times their displacements, so
enhancement=1 is the normal display, and
enhancement=0 is the undistorted mesh.
-
Added the Cross Section dashboard to the Drawers, for
plotting the displayed quantity along a line.
Currently it only puts uniformly spaced points on the
line; in a later version it will optionally put points
only at the element boundaries.
-
Added an output/crosssection menu, giving
access to the functionality of the Cross Section
dashboard even in text mode.
-
Changed
output/stress/statistics/type=invariant to
eigenvalues and added a new option called
invariants that prints statistics on the
first, second, and third invariants of the stress. The
same change applies to
output/strain/statistics/type.
-
Fixed a obscure bug that prevented Drawers from being
updated if they had been opened but were not visible
when the mesh was created.
1.0.8 beta 25
-
The Cross Section dashboard can plot with unevenly
spaced points. It tries to put points only at the
element boundaries.
1.0.8 beta 26
-
Moved the enhancement variable from the main menu to
the graphics menu. This wouldn't normally merit its
own version number, but I was updating the manual and
didn't want it to get ahead of the program.
1.0.8 beta 27
-
Changed the way in which the Cross Section commands
work with non-uniformly spaced points. Now points are
placed at element boundaries, regardless of whether or
not the function being plotted changes value.
-
Split the /ouptut/crosssection menu into two submenus,
named "uniform" and "nonuniform", for uniformly and
nonuniformly spaced plot points. In the original
scheme it was impossible to set the tolerance for
nonuniformly spaced points.
1.0.8 beta 28
-
Added output for two-dimensional shear stress, which is only
guaranteed to be correct if the out-of-plane stresses are zero.
1.0.8 beta 29
-
Fixed a bug in the force output. The thermal stresses
hadn't been included.
-
Added the "pause" command.
1.0.8 beta 30
-
Added a "rename" command for element and node groups.
-
Added a pause command to put in scripts.
1.0.8 beta 31
-
Made "output/stress/statistics" use the original
element areas for weights, rather than the disorted
areas.
-
Check for and warn about nonpositive areas after equilibrating.
-
Added "output/strain/statistics" menu, which does for
total strain what the "output/stress/statistics" menu
does for stress.
-
Fixed the arclength button on the cross section dashboard.
-
Added "output/current_area/<group>" and
"output/original_area/<group>" to get the total
area of a group of elements.
-
Added "output/stress/all" and "output/strain/all" to
get average stress and strain on the whole system.
-
After equilibration, move disconnected nodes to the
average position of their neighbors, so that they
don't screw up the warning about nonpositive element
areas.
-
Avoid nan's in statistics output when roundoff error
makes the variance slightly negative.
1.0.8 beta 32
-
Give a warning when one or both ends of the line are
off the edge of the grid in the cross section
dashboard, and try to do something sensible.
1.0.8 beta 32
-
Give a warning when one or both ends of the line are
off the edge of the grid in the cross section
dashboard, and try to do something sensible.
1.0.8 beta 33
-
Don't close the whole program when closing the color
browser with a window-manager close button.
|
|
version 1.1 |
9/00-10/00
-
Added thermal fields.
-
Changed the way that enslaved degrees of freedom are
implemented. Now it's possible to enslave two groups
that share the same degrees of freedom.
-
Changed the way that boundary conditions and
distortions are stored in the goof files. Instead of
storing the command list, the distortion and bc state
of each nodegroup is stored with the group
information. Storing the command list could lead to
errors when a group had been enslaved and then
emancipated before writing the goof file.
|
version 1.1.1 |
10/13/00
-
Merged source for thermal and regular
versions. Compiling with the compiler flag -DTHERMAL
gives the thermal version. Both versions now have the
same version number.
-
Added Doug Twisselmann's Twissel Element (isotropic
with a T independent stress free strain). The strain
is proportional to a fictive temperature, which
appears in the main OOF menu.
|
version 1.1.2 |
10/17/00
-
Workaround for XForms bug which makes command line
argument parsing fail when the program name has more
than one dot in it (as in "oof1.1.1").
|
version 1.1.3 |
10/19/00
-
Added the gas element (thermal conductivity but no
elasticity) to the thermal version. The elastic-only
version is unchanged.
|
version 1.1.4 |
10/00
-
Added select/nodes/nearest and
select/nodes/rectangle commands for selecting
nodes in text mode.
-
Added output/position/group commands
to print the average position of a node group.
|
version 1.1.5 |
11/02/00
|
version 1.1.6 |
11/00
-
Fixed a meaningless error message when the
-start command line option was used and
-file wasn't.
-
Reworked the way distortions and enslavements are
implemented, since they weren't working correctly for
groups which were both fixed and enslaved. There's
not much need for fixed enslaved groups, but they
could arise by accident.
-
Added "bc/emancipate/all".
|
version 1.1.7 |
11/00
-
Fixed a bug that was causing problems in reading
configuration files in ppm2oof. Don't know if it was
causing problems in oof, though...
-
Added "output/comment" to allow annotation in files
written by "output/tee".
-
Commands that affect the boundary conditions applied
via node groups no longer apply those boundary
conditions immediately. The boundary conditions are
postponed until abolutely needed, in order to speed up
their application to multiple groups. A consequence
is that the display may not reflect the current
boundary conditions. Use "bc/apply" to force the
boundary conditions to be applied immediately.
Clicking on a node in the NodeInfo dashboard will also
apply the boundary conditions.
|
version 1.1.8 |
1/11/01
-
Restored the preconditioner variable to the root menu
in the elastic version of the program. It had somehow
been lost when the thermal code was added.
|
version 1.1.9 |
2/01
-
Added "output/traction" to print the dot product of
the stress with the surface normal, integrated over
the length of a surface defined by a nodegroup. It
should be the same as "output/force", but may treat
corners better in some cases. It will get confused if
the nodegroup does not represent a real edge.
-
The "Save" button in the graphics windows will now
generate PostScript output if the output file name
ends in ".ps" or ".eps".
|
version 1.1.10 |
6/4/01
-
Reordered operations at exit to avoid a rare
segmentation fault.
|
version 1.1.11 |
6/27/01
-
Added the "effective property" menu to compute
effective macroscopic properties.
|
version 1.1.12 |
11/01
-
Added "gradyation" element requested by Grady White.
-
Fixed the "effective property" menu commands in the
thermal version.
|
version 1.1.13 |
11/30/01
-
Fixed the "effective property" menu commands, again.
They hadn't been dividing by the edge length.
|
version 1.1.14 |
11/30/01
-
Fixed a bug that caused crashes when equilibrating
with empty elements in the thermal version.
|
version 1.1.15 |
12/11/01
-
Fixed errant factors of 0.5 in the calculation of the
TrigonalA modulus. C46 and C56 were half the size
they should have been.
|
version 1.1.16 |
02/05/02
-
Minor changes to make gcc 2.96 happy. No additional
features.
|
version 1.1.17 |
10/16/02
-
Modifications to allow compilation with gcc 3.1. No additional
features.
|
version 1.1.18 |
8/21/03
|
version 1.1.19 |
10/31/03
-
Minor changes to accomodate gcc3.3 and OS X 10.3.
|
version 1.1.20 |
2/18/05
-
New output routines for saving data in OOF2
format, and minor fixes to accomodate newer compilers.
|
version 1.1.21 |
8/1/05
-
Minor changes to accomodate gcc 3.4.
|
version 1.1.22 |
8/21/07
-
Minor changes to accomodate gcc 4.1.
|
