Week- 8 - Solid meshing

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

Procedure :

• First step is to import the IGS file that is provided into the ANSA software
• Then apply topo to object
• After applying topo check for geometry errors, if found errors resolve those errors, and then proceed to the next process.

• After all errors are resolved, give mesh parameters and criteria that are provided in this case Min length - 0.5, max length 2, target length 1
• Choose the mesh type as Tria and Ortho tria.
• Use Ortho tria near the features and use tria in the remaining places for better mesh quality and flow.
• Use spot mesh, select the features first, and then move to the remaining parts.
• After the mesh is done check for the off elements and eliminate those by reconstructing them again.

• After meshing is done go to the volumetric mesh, Here ANSA cannot identify closed solid volume objects, so define the volume by selecting the object.
• Apply the mesh criteria provided in this condition Tet collapse- 0.2, and eliminate errors without disturbing surfaces like forming dents, etc.
• Then ANSA by default shows the unmeshed volumes that are present.
• Then apply Tetra Rapid on the solid objects individually.
• Then we can we see volume mesh is done. In order to check if the mesh is successful use bound, if the grid turns red then it is a volumetric part.

Learning Outcomes:

• By this we can able to understand the mesh pattern in this solid object.
• We are able to mesh the object and eliminate errors.
• We learnt how volume mesh will be done and the procedure to be followed.

Conclusion:

• Mesh is generated succesfully on surface of solid and volume mesh is also generated.
