pw:: UnstructuredSolver

$solver get/setStopWhenFullLayersNotMet value

This attribute controls whether the pw::Solver.run command will stop when the requested number of full layers is not met by the solver.

Type

This attribute is a boolean value.

Default

The default for this attribute is False, which means the run command will not stop if the requested number of full alyers is not met.

$solver get/setAllowIncomplete value

This attribute controls whether the pw::Solver.run command will throw an error if initialization produces an incomplete grid.  This can occur during T-Rex initialization when the isotropic tet generation failed, but the T-Rex cells were retained.

Type

This attribute is a boolean value.

Default

The default for this attribute is False, which means the pw::Solver.run command will throw an error if an incomplete block is created.

$solver get/setOversetAdaptation value

This attribute controls whether the pw::Solver.run command will perform refinement based on overset assembly length scales.

Type

This attribute is a boolean value.

Default

The default for this attribute is False, which means the pw::Solver.run command will perform standard refinement (no overset assembly contribution).

$solver run ?-entities ents? ?steps | method ?method_args??

This action runs the solver.

Parameters

Returns

This action returns nothing.

Information

This command supports progress updates.  Unlike most commands that support progress updates, if the user aborts this command, instead of reverting to the previous state the entities being solved will be left as is.

Example

Code

$solver getCurrentStage

This action gets the current stage of the unstructured solver.

Parameters

This action has no parameters.

Returns

This action returns the current stage; None | PushAttributes | TRex | Isotropic

$solver getCurrentEntity

This action gets the current entity of the unstructured solver.
