EREFINE

EREFINE, NE1, NE2, NINC, LEVEL, DEPTH, POST, RETAIN
Refines the mesh around specified elements.

Valid Products: Pro | Premium | Enterprise | PrepPost | Solver | AS add-on

NE1, NE2, NINC

Elements (NE1 to NE2 in increments of NINC) around which the mesh is to be refined. NE2 defaults to NE1, and NINC defaults to 1. If NE1 = ALL, NE2 and NINC are ignored and all selected elements are used for refinement. If NE1 = P, graphical picking is enabled and all remaining command fields are ignored (valid only in the GUI). A component name may also be substituted for NE1 (NE2 and NINC are ignored).

LEVEL

Amount of refinement to be done. Specify the value of LEVEL as an integer from 1 to 5, where a value of 1 provides minimal refinement, and a value of 5 provides maximum refinement (defaults to 1).

DEPTH

Depth of mesh refinement in terms of number of elements outward from the indicated elements, NE1 to NE2 (defaults to 0).

POST

Type of postprocessing to be done after element splitting, in order to improve element quality:

OFF

 — 

No postprocessing will be done.

SMOOTH

 — 

Smoothing will be done. Node locations may change.

CLEAN

 — 

Smoothing and cleanup will be done. Existing elements may be deleted, and node locations may change (default).

RETAIN

Flag indicating whether quadrilateral elements must be retained in the refinement of an all-quadrilateral mesh. (The program ignores the RETAIN argument when you are refining anything other than a quadrilateral mesh.)

ON

 — 

The final mesh will be composed entirely of quadrilateral elements, regardless of the element quality (default).

OFF

 — 

The final mesh may include some triangular elements in order to maintain element quality and provide transitioning.

Notes

EREFINE refines all area elements and tetrahedral volume elements adjacent to the specified elements.

Mesh refinement is not available on a solid model containing initial conditions at nodes (IC), coupled nodes (CP family of commands), constraint equations (CE family of commands), or boundary conditions or loads applied directly to any of its nodes or elements. This restriction applies to nodes and elements anywhere in the model, not just in the region where you want to request mesh refinement. If you have detached the mesh from the solid model, disable postprocessing cleanup or smoothing (POST = OFF) after refinement to preserve the element attributes.

For more information about mesh refinement, see Revising Your Model.

This command is also valid for rezoning.
