Auto Mesh: Planar Area

Function

Auto Mesh - Planar Area automatically generates 2D meshes in domains defined by only boundary lines on a plane.

Call

 Mesh > Auto Mesh > Planar Area

<Auto-Mesh Planar Area>

Select Edge(s)

Select boundary edges (Edge) of planar domains on which meshes will be created.
 

Select Interior Vertex(es)

Select Interior Vertices contained within the defined domains for which meshes will be created.  Nodes will be created at the selected vertices for elements.
 

Mesh Size

Element Size

Specify the element size.
Division

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

Attribute

Mesh Set

<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 Inner Domain

Inner Domains are domains that exist inside the domains defined by the selected boundary edges.  Mesh Inner Domain determines whether or not to generate meshes in the inner domains.
 

Include Interior Edges

Select Interior Edges contained within defined area for which 2D meshes will be created.
 

Refinement Factor

Mesh Set

Register Each Area Independently

When creating meshes for more than one domain, this option registers the mesh of each domain in a separate mesh set.
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.

Merge Nodes

Generate Mid-side Nodes

Notes

Inner domain represents an area which is not connected to outer boundary lines. The above example has two inner domains.  The result mesh on the left is generated without Mesh Inner  Domain option, and the other is generated with it.

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.

In cases where the mesh fails to generate, refer to Remove Edge.

Meshing 2D Elements in a Planar Domain

<Instruction>

1. Select Edge(s) which are going to be boundary of 2D Mesh.

2. Select Interior Vertex(es) to be considered in mesh generation.

3. Choose a meshing algorithm (Refer to Meshing Algorithm) Above example has meshed with Grid Mesher.

4. Make sure sizing method is in Element Size (Refer to Size Control>On Face…).

5. Enter 1 in Mesh Size.

6. Click button to assign Attribute to the faces.

7. Click [OK] button.
