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.
