Week- 5 - Solid meshing

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

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

S.No	Quality Criteria	Value
1	Tet collapse	0.2

Cad:

PROCEDURE

• The rearview model is imported to ANSA file>open

• 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.

Shell mesh;

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

3d meshing

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

QUALITY:

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

Conclusion:

Performed tetra meshing with all elements satisfying the given quality criteria.
