Required parameters

ELSET
Set this parameter equal to the name of the element set containing the elements that will be activated during the analysis.
NAME
Set this parameter equal to a label that will be used to refer to this progressive element activation.

Optional parameters

FOLLOW DEFORMATION

Set FOLLOW DEFORMATION=NO (default) for elements that have not yet been activated to remain in their initial positions.

Set FOLLOW DEFORMATION=YES for elements that have not yet been activated to follow the movement of the active elements to prevent their excessive deformation.

FREE SURFACE

Set FREE SURFACE=NONE (default) for convection or radiation boundary conditions to be applied on the full exposed areas of the element facets. If the element is partially filled, the cooling is applied on the full element facet area.

Set FREE SURFACE=FACET for user subroutine UEPACTIVATIONFACET to be called at the start of the increment for each element. You can prescribe the facet area and the increment time for which the facet area is exposed for cooling. You can prescribe the exposed areas on the element facets and the internal cut facet for partial element activation. This feature is supported only for lower-order elements.
