Boolean operation on solids to get matching nodes

Altair Forum User

Hello,

 

I have two solids which are in contact (Figures 1, 2 & 3). Correct me if I'm wrong, but my understanding is to use theboolean operations in solid edit  [{A-B,B} (cut A with B method)] to get a common surface so that the two meshes have matching nodes at the end of the workflow. One problem I find with this method is that even if I toggle off some edges they appear again after a boleean operation. Another problem is the boundary edges (Figure 4) of the common surface between the two objects in contact are sharp and the mesh generated will be bad. Is there a way to solve this or altogether a different method please?

 

Model is attached (Hypermesh 2017)

Thank you for your help.

try to use 'autoclean up' tool.

but you should add mesh parameters which you use for meshing yellow body.  you can create this. (i am talking about shell mesh, because autoclean up uses this params)

better to use smaller el size parameters than your mesh will be. exmpl if you want 2 mm tetra you should use 1 mm for clean up tool.
