modmsh

Mapdl.modmsh(lab='', **kwargs)

Controls the relationship of the solid model and the FE model.

APDL Command: MODMSH

Parameters
lab

Relationship key:

STAT - Gives status of command (default). This applies only to the CHECK option (no

status is provided for the DETACH option).

NOCHECK - Deactivates the checking of the solid model and the finite element model.

Allows elements and nodes generated with the mesh commands to be modified directly (EMODIF, NMODIF, EDELE, NDELE, etc.). Also deactivates solid model hierarchical checking so that areas attached to volumes may be deleted etc.

CHECK - Reactivates future checking of the solid model.

DETACH - Releases all associativity between the current solid model and finite element

model. ANSYS deletes any element attributes that were assigned to the affected solid model entities through default attributes (that is, through the TYPE, REAL, MAT, SECNUM, and ESYS command settings and a subsequent meshing operation). However, attributes that were assigned directly to the solid model entities (via the KATT, LATT, AATT, and VATT commands) are not deleted.

Notes

Affects the relationship of the solid model (keypoints, lines, areas, volumes) and the finite element model (nodes, elements, and boundary conditions).

Specify Lab = NOCHECK carefully. By deactivating checking, the solid model database can be corrupted by subsequent operations.

After specifying Lab = DETACH, it is no longer possible to select or define finite element model items in terms of the detached solid model or to clear the mesh.
