Week- 5 - Solid meshing

Aim :- For the given Rear view mirror component, check for the geometrical errors and mesh the Surfaces with the given 2D element Quality criterias given below.

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

Use tetra elements to mesh the Volumes defined in the model and check for the below quality after Volume meshing.

S.No	Quality Criteria	Value
1	Tet collapse	0.2

Procedure :-

Step 1 :- Import the model.

File - open -selelct the iges file -open.

Step 2 :- Topo the given model and orinetation also .

Topo - Faces - topo -selelct the model -topo

Topo - Faces - orient - select all.

Step 3 :- Check for geometry clean up.

Check - geometry - execute .

To fix the eroors

Select the all erros - rigt click - fix.

Step 4 :- Toggle the line (to passes the minimum quality)

Topo - faces - join -select the line want to supperess.

after cleanup the geometry .

Step 5 :- Assign the quality parameters.

Step 6 :- Assign mesh parameters.

Step 7 :-Generating tria mesh

Mesh - mesh generation - spot mesh-select the surface - mesh.

Changing the mesh type for flat surfacse as tria.

After completion of meshing .

Step 8 :- Generating volume mesh.

volume mesh - define - detect on visible - ok.

After defined volume - select the model - generate tetra FEM .

Step 9- assigning tet collapse in Quality .

Final Model :

Passes all quality parameters.

Learning Outcomes :-

*Learned about topo the surfaces and learened about the fix the geometry errors.

*Learned about generating trias mesh in epend surfaces .

*Learned About generating volume tetra mesh.

Got a knowledge tp passed the quality criteria.
