Get a Hexahedral Mesh

[JKbear]

Hi,

I am trying to get a hexahedral mesh from a 3-D geometry, but I can’t find any specific parameter to control the mesh to be hexahedron.

When I use “volume all scheme tetmesh”, it works fine. But I do not know how to change it to get a mesh with hex elements.

Any help or suggestion will be appreciated.

Thanks!

You can specify a mesh scheme using the command line or the GUI command panel (Mesh->Volume->Mesh). Automatically Calculate is the default mesh scheme. Trelis will try to map and sweep the volumes in your model as best as it can. However, depending on the volume, it may not be able to determine the source and target surfaces automatically. You can use the Sweep scheme to manually set the source and target surfaces.

Please see csimsoft.com/help/trelishelp.htm and search for information on Meshing Schemes. Explicit schemes are used for hex meshing:

Map
Submap
Sweep
Sphere
Polyhedron

To be able to map and sweep, you may need to decompose the model into meshable volumes.

Thanks for your quick and helpful reply!
I will try as you suggested.

Thanks again.
