xfdata#
- SpecialPurpose.xfdata(enrichmentid='', lsm='', elemnum='', nodenum='', phi='', psi='', **kwargs)#
Defines a crack in the model by specifying nodal level set values
Mechanical APDL Command: XFDATA
- Parameters:
- enrichmentid
str Name of the enrichment specified via the associated xfenrich command.
- lsm
str Indicates that level set values are being specified (default).
- elemnum
str Element number.
- nodenum
str Node number associated with the specified element
ELNUM.- phi
str Signed normal distance of the node from the crack.
- psi
str Signed normal distance of the node from the crack tip (or crack front). Used only in the singularity-based XFEM method.
- enrichmentid
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.
