Week- 8 - Solid meshing

Aim : 

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 :

1. Open file in ANSA, Orient and Topo the whole Model

2. Check for Geometry and try fixing by selecting all error, select fix.

3. After fixing all the errors. Visible only one Psheel Property.

4. Go to the classic mesh. Give 'Mesh parameter' as given, give 'Parameter Length' to the component, Give 'Quality Criteria' as given. After that mesh the surfaces. During meshing for Curves/Filet area use element type as 'ortho tria' and for flat surfaces use element type as 'tria'. After meshing click on Hidden feature and see if the area are failing . If they are failing fix using 'Join', 'Reconstruct', 'Smooth', 'Num+/-' as per conditions. For 2D Elements, Only check for Min length and Max length errors. If none of them are failing then the meshing is ok.

5. After that go to Volume Mesh and go to Define the select Detect on- Visible then press ok. The component is defined. we can name to any name.

6. After we can mesh the volume with the 'Tetra Rapid' or 'Tetra FEM'. The difference between Tetra Rapid and Tetra FEM, is in Tetra FEM the mesh will be uniform. we can rename the property as per need and view in Properties.

7. After that For 3D Elements,check Tet Collapse errors. If it not failing then 3D meshing is succesfully completed for 1st component.

8. Repeat the same procedure for other Properties also and check the whole assembly if there are some error. if none of them are failing then 3D Meshing for Rear View Mirror is Done.
