Procedure :
- Import the CAD geometry .
- Check for any geometrical errors or topological errors.
- Defeaturing any construction lines required where the element gets failed.
- Give perimeter elemental length as 1 for checking any CAD issues / errors.
- Give the quality parameters.
- Using spot mesh in the Shell Mesh window apply mesh on the surfaces.
- Apply Tria mesh on the plane surfaces and Ortho tria on curved , fillet as the time taking for generating volume mesh using Ortho tria is much higher than normal tria .
- Check for any elemental failures for minimum or maximum lengths.
- Avoid any kinks on the surfaces.
- In the Solid mesh window > Define > define the cad after shell mesh for creating volume mesh.
- Using Tetra Rapid or Tetra FEM generated volume mesh on the surface.
- Check for any Elemental failures.
Learning outcomes :
- Where to apply normal tia mesh and ortho tria mesh
- MV free command
- To create volume mesh using Unstructured mesh (Tetra Rapid / Tetra FEM)
Conclusion :
For given rear view mirror cleared geometrical error , and created Volume mesh using ANSA following the given quality criteria.
