Discussion about meshing issues.

3D Mesh

Postby Cubit User » Mon Jun 25, 2012 3:03 pm

I need to make a full 3D variant of the axisymmetric plate with a hole. I've made it most of the way there, but am having some issues meshing the volume. My first idea was to create the volume with the hole, then mesh the hole and grade the mesh towards the opposite surfaces.

I was able to mesh all 6 surfaces as well as the surface of the hole in this and other manners. I then tried meshing the volume using either scheme auto, or scheme sweep, where I pick a couple surfaces to sweep between. However, neither of those options seems to work.

Thus, my questions are:
1. How can I mesh the volume from the mesh of the surfaces?
2. Is this the best way to go about this?

Here is the journal file:

This is a shape that can be meshed with the scheme "polyhedron". After playing your journal file, execute the commands:

delete mesh
vol all scheme poly
mesh vol all

That should generate your full 3D mesh. To control the grading of the mesh, I would first mesh the curves using a bias scheme before meshing the volume.

Is there any specific option for sizing function for edge->face, edge->volume or face->volume?? Please help me with that....
