Semi-coherent meshed part

Hello,
how would one mesh a multi-body part with shared nodes, but exclude some adjacent faces from the meshing algorithm?

For example I wanna have common nodes between weld but not between sheets.

Thank you

yes via code_aster using liasion_mail is possible :-)

liasion_mail creates just "bonded contact" between parts. I want to have common nodes.

Re: Semi-coherent meshed part

Hi,

Assuming you are using Salome, just partitioning your geom,
mesh it as one whole (this makes fully conformal mesh on all internal faces of the partitioned geometry),
then use the Duplicate Nodes or/and Elements from the menu Modification->Transformation.
Either the 1st or the 4th option could work, but require different preparation (grouping) and post treatment (re-merging of some nodes).

This process will result fully identical element shapes and node location on the both sides of your interface, but with duplicated nodes! The rest of your mesh is fully merged.

BR.

Re: Semi-coherent meshed part

Yes. Could you upload hdf?

However I guess I solved it by using groups and node merge.
Groups are working quite well in salome so far.
