Element Info Dashboard

Figure 5.5: The Element Info Dashboard.
% a clumsy but documented latex2html hack

When the Element Info Dashboard is open, clicking the mouse on an element in the image prints information about the element to the Message Window. When the mouse is over the Drawing Area the cursor changes to a question mark. The element being queried is under the dot at the bottom of the question mark.

The check boxes in the Dashboard determine what information is printed.

mouse position
The coordinates of the mouse in physical units.

element type
The type of element, as described in Chapter 4.

element index
The index of the element. Each element has a unique integer index, which can be used to identify it in the output files created by the /output/individual commands (Section 3.32). Note that the element index can change if the grid is modified and then equilibrated!

node indices
The indices of the nodes at the corners of the elements. These indices may be used in the command /output/node, for example. They are also used internally in the .goof file.

intrinsic gray
The gray value of the element, as described in Chapter 4.

element parameters
Again, see Chapter 4. These are the arguments to the function that was used to create the element.

stress and strain
The stress and/or strain in the element. Which components of stress and strain are printed depend on the settings of the smaller check boxes below. Note that strain can be queried even in a Stress Drawer, and vice versa.

energy density
The elastic energy density in the element.

The check boxes determining which components of stress and strain are printed are:

The Cartesian components in the screen's coordinate system.

The first, second, and third invariants, as described in Section 5.1.

The eigenvalues, as well as their orientations. Orientations are either a single number or a pair in square brackets. The pair $(\theta, \phi)$ is the standard representation of an angle on the unit sphere; i.e, $\theta$ is the declination from the $z$ axis in degrees, and $\phi$ is the rotation about the $z$ axis, as measured counterclockwise from the $x$ axis. If $\phi=\pi/2$, then only $\theta$ is given.
