OOF2: The Manual
The Fields & Equations Page specifies which Fields
are
defined on the Mesh
which Equations
are active. It has
three parts, as shown in Figure 3.20.
The Subproblem Chooser at the top of the page specifies which SubProblem
is being operated upon. The Field Pane sets various
properties of the Fields
. The Equation Pane activates
Equations
.
The Field Pane specifies which Fields
are defined on the
SubProblem
, and sets attributes of those Fields
. The checkboxes
for each Field
correspond to commands in the OOF.Mesh.Field menu.

Toggling the defines and undefines the
checkboxField
. TheMesh
only stores values for definedFields
. 
Toggling the activates and deactivates the
checkboxField
. TheEquations
only solve for activeFields
. 
OOF2 generalizes the standard concept of planestrain to apply to arbitrary coupled
Fields
. Toggling the button determines whether or not theField
has outofplane derivatives, by invoking OOF.Mesh.Field.In_Plane or OOF.Mesh.Field.Out_of_Plane. The counterpart to generalized planestrain, planeflux, is invoked by activating the appropriate equation in the Equation Pane.A
Field
that is inplane on oneSubProblem
in aMesh
must be inplane on allSubProblems
in thatMesh
.
The SubProblem
, possibly in
another Mesh
.
The Equation Pane simply contains a list of the Equations
that OOF2 can solve, and checkboxes which activate
and deactivate
them for the current SubProblem
. Equations
will be solved
only if they are active, if the Fields
they use are defined,
and if there are Material
Properties
in the SubProblem
that make contributions to them.

, possibly in a different Mesh
.
