Week- 5 - Solid meshing

OBJECTIVE

To perform Tetra - Mesh for the Rearview mirror with the quality parameters as given below

2D

S.No	Quality Criteria	Value
1	Target/Average length	1
2	Minimum Length	0.5
3	Maximum Length	2

3D

S.No	Quality Criteria	Value
1	Tet collapse	0.2

CAD

PROCEDURE

• The rearview model is imported to ANSA file>open
• Then the model is organized to different collectors based on their volume

• Then model is checked for geometrical using the checks manager >geometry

• Then the mesh parameters and quality criteria is assigned

• Now 2d mesh is performed over the surfaces with element type(tria and ortho tria).ortho_tria elements were used at the surface like fillets and curvature to capture features.

• First, the fillets, curvature regions were meshed with element type{othotria} and finally, the remaining plane surface are capture using trias

• The elements failing for minium and maximum were optimized using reconstruct, split and smooth

3d

• Now the volume of the components were defined and TETRA Rapid mesh command is performed over the defined volume

TET ELEMENTS

QUALITY

The elements failing for tet collapse is optimized using the move option without affecting mesh on the surface

Results:

1. Performed geometry clean-up.
2. Performed tetra meshing with all elements passing the quality criteria.
