Week- 5 - Solid meshing

1. OBJECTIVE:

To mesh the given geometry using tetramesh

2. PRE-REQUISITES:

1. To clean the imported geometry
2. To perform the tria shell mesh
3. To perform the geometry checks, material checks.
4. To perform the volume mesh from generated tria mesh
5. To perform checks for quality of mesh.

3. GEOMETRY CLEAN-UP:

It is important to study the imported geometry.

Topology clean up:

Topo deck >> Faces >> Topo >> select geometry >> click ok.

Orientation:

Topo deck >> faces >> orient >> Auto >> grey vol outside >> click ok

Geometry check:

Geometry check >> execute >> delete triple cons >> delete sharp edges (needle face)

4. GEOMETRY DISINTEGRATION:

Geometry is disintegrated into multi lock views to ease up the mesh. To mesh the areas not directly visible.

5. MESH

Mesh criteria:

f11>>pshell>>min size = 0.5 >> max size = 2>>solid>>tet collapse = 0.2
