Hi YukeshKumar,


 


Please let us know what is the type analysis are you going to work on with this component?


 


If this is a rigid component you can use Wrap mesh which captures the boundaries but the mesh may not be a good quality mesh.


 


If this is a flexible component, you can Hex Mesh this, but time taking process with this component. Use defeature options to remove fillets (Geom Page>> defeature).


 


Or, to save time you can use 2nd order tetra elements to mesh this.

It's not so easy to build a full HEX meshing for this kind of geometry. The solution is maybe :


  1. Mixte HEX/PEN/PYRA/TET mesh
  2. Full TET10 mesh

i think this structural analysis , but  must need hexa and penta , not tet  sir 

 

If you WANT always hex/penta meshing, I would like to say "Good luck!" :)

Why TET10 mesh? Is that more precise than the TET4 mesh?

If you ask here this question, you need read some (good) FE textbook :)

I do agree with you, but could you mind recommend some good textbook to me?Thank you.

Google is your friend.

If you need only one advise, here's mine : "Never use TET4 mesh for serious work! NEVER!"
