XFDATA

XFDATA, EnrichmentID, LSM or -- , ELEMNUM, NODENUM, PHI, PSI
Defines a crack in the model by specifying nodal level set values

PREP7: Special Purpose

Compatible Products: – | – | – | Enterprise | Ent PP | Ent Solver | –

EnrichmentID: Name of the enrichment specified via the associated XFENRICH command.
LSM: Indicates that level set values are being specified (default).
ELEMNUM: Element number.
NODENUM: Node number associated with the specified element ELNUM.
PHI: Signed normal distance of the node from the crack.
PSI: Signed normal distance of the node from the crack tip (or crack front). Used only in the singularity-based XFEM method.

Notes

Issue the XFDATA command multiple times as needed to specify nodal level set values for all nodes of an element.

This command is valid in PREP7 (/PREP7) only.
