Blank Mesh

Purpose:

This interface is primarily intended for mesh generation of blanks for metalforming simulations, but it may also have applications in other areas.

Function:

4 Pnts : Using 4 Corner Nodes (of a blank) and Element Size to generate a mesh.

Rect : Mesh rectangle of given Length and Width with element size or number of elements.

Curve : Allows a mesh to be created on an enclosed curve. Element alignment can be along global axis or user defined. Mesh boundary options are as follows: Smoothed, Left Jagged (and optionally filled with trias), or No-Trim (creates a rectangular blank without trimming.

Refine£şMulti-level refine.

Sample:

no sample.
