- Figure 1 – BMesh Four Points
Purpose:
This interface is primarily intended for mesh generation of blanks for metalforming simulations, but it may also have applications in other areas. Three methods of blank mesh generation are available:
- 4 Corner Nodes (of a blank) + Element Size
- Rectangle of given Length and Width + Element Size or Number of Elements
- By Curve
The By Curve method allows a mesh to be created on an enclosed curve. Curves can be imported using IGES, VDA, DXF, or XYZ points. Element alignment can be along global axis or user defined by using the Element Alignment popup dialog. Mesh boundary options are as follows: Smoothed, Left Jagged (and optionally filled with trias), or No-Trim (creates a rectangular blank without trimming
Controls:
Get a new part ID from the current model
- PID: Pick part ID for the current blank
Four Points – Generate a blank by giving four points
