xfdata#

Mapdl.xfdata(enrichmentid='', lsm='', elemnum='', nodenum='', phi='', psi='', **kwargs)#

Defines a crack in the model by specifying nodal level set values

APDL Command: XFDATA

Parameters:
enrichmentid

Name of the enrichment specified via the associated XFENRICH command.

lsm (or blank)

Specify LSM to indicate that level set values (PHI and optional PSI) are specified.

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.
