Auto Mesh

Purpose:

This interface is for surface mesh generation. Two meshing methods are available: By size and By Deviation.

Function:

Auto Mesh : Size mode creates uniformly sized elements

Tool Mesh : Specifically for metalforming applications where surfaces may contain very small radii that need to be meshed accurately, and at the same time have flat areas that require a relatively coarse mesh. Tool meshing requirements are very different from those of structural finite element analysis.

Sample:

Two kind mesh comparison : show the difference between size-based and deviation-based.

Automesh:

  • Size : Select the size mode.

  • Deviation : Select the deviation mode.

  • Mesh Type : Generate triangle mesh only or mixed.

  • Elem Size : Enter average element size.

  • Compute : Compute mesh parameter by model extend.

  • Reset : Reset mesh parameter to default.

  • Show Meshed Boundaries : Before Accept and After Mesh, will become sensitive. Show the boundary node as blank square.

  • Auto remesh boundary : Before Accept and After Mesh, will become sensitive. On the boundary, left click to increase the node num and right click to decrease it. Then automesh it according to the new boundary.

  • Manual remesh boundary : Before Accept and After Mesh, will become sensitive. On the boundary, left click to add a new node and right click to remove a node. Then automesh it according to the new boundary.

  • Mesh By GPart : The mesh generated from same GPart will be organized into same part.

  • Ignored Hole Size : Holes under specified size will be ignored.

  • Part ID : Assign new generated mesh to this part or create a new part if this part id doesn't exist.

  • Mesh : Generate shell mesh for selected surfaces.

  • Reject : Reject the last operation.

  • Accept : Accept the last operation.

  • Done : Exit this dialog.

Toolmesh :

  • Max Elem Size: Enter maximum element size.

  • Min Elem Size: Enter minimum element size.

  • Max Deviation: Enter maximum deviation ratio.

  • Max Angle: Enter maximum feature angle.
