Boundary conditions

Setup tree: Boundary conditions

  • Control: action (ToolButton2)
  • Shown when: Results.ready && !CaseState.patchesMatchMesh
  • Control: value (ValueField)
  • Value modes: none (plain entry)

Named as OpenFOAM will see it — letters, digits and underscores.

  • Control: action (ToolButton2)
  • Enabled when: listRoot.pendingName !== "" && CaseState.patchNameIssue(listRoot.pendingName, -1) === ""

The application checks these before a run and reports them in the Problems tab against this step.

Severity Message
error No patch is set to ‘Wave inlet’, so constant/waveProperties names a patch that generates nothing.
info Nothing on the boundary fixes the pressure level, so pRefCell 0 and pRefValue 0 are written into fvSolution to pin it. Only differences in pressure mean anything in a closed domain.
error This case is set to two-dimensional but no patch is Empty (2D), so the solver will treat it as 3D. The side faces have to be empty for the direction to be dropped.
error An axisymmetric case needs exactly two wedge patches, one each side of the axis. This case has ….
error A case cannot be both two-dimensional and axisymmetric - empty and wedge patches are alternative ways of removing the same direction.

marks a value the application computes at run time, so the source carries no fixed text for it.
