Auto Mesh: 4-Edge Area

Function

Auto Mesh–4 Edge Area automatically generates 2D mesh in a domain defined by 4 boundary lines in space.

Call

Mesh > Auto Mesh > 4-Edge Area

<Auto-Mesh 4-Edge Area>

Select Edge(s)

Select boundary edges (Edge) of a domain in space for mesh generation.  There must be no more or no less than four boundary edges
 

Mesh Size

Element Size

Specify the element size.
Division

Specify the number of divisions at the boundary edges of the shape for a meshing operation.

<Advanced Option>

Mesher

Select mesh generation algorithm and element type.
 

Loop Mesher

Grid Mesher
 

Delaunay Mesher

Generate Offset Elements

Construct meshes at the boundaries of the selected planar domains first, and then expand the meshes inward.  This command may be applicable for generating quadrilateral meshes using the Loop Mesher or the Grid Mesher.

Mesh Set

Merge Nodes

Generate Mid-side Nodes

Register Mesh Function

Using this option, the generated meshes are not registered in Mesh Set, but rather they are registered in Mesh Object under Mesh of the Works Tree. Mesh object has the meshed history so that user can conveniently re-mesh it from the Context Menu.

Notes

The program provides re-meshing functions for Auto-generated Mesh using its Geometric Shape. However, Auto-Mesh 4 Edge Area is generating a mesh without actual Geometric Shape. It only uses boundary edges. In this case, it provides Mesh Function option which can be used for re-meshing after initial generation.

Meshing 2D Elements using boundary edges in 3D space

<Instruction>

1. Select 4 Edges which are going to be boundary of 2D Mesh.

2. Choose a meshing algorithm (Refer to Meshing Algorithm).

3. Make sure sizing method is in Element Size Size Control>On Face…).

4. Enter 15 in Mesh Size.

5. Click button to assign Attribute to the faces.

6. Click [OK] button.
