Hi,
I have a step geometry imported into geom module as compund called “contact”. I exploded it and created several groups. Then i created submesh on some groups and a mesh on contact compound and generated mesh successfully. Below some figures.
Now I discover that i need to refine some areas of mesh. To do so I create some more geometry in geom module( vertices) and try partitioning the contact compound with those vertices.
However during this operation all groups and their corresponding submeshes are lost and I have to recreate them again. Basically I want to refine the ege between two vertices created on e4 edge group by assigining them new submesh. But as the divided edge does not belong to original compund, i cannot create submesh on it.
Is there a way to restore groups and submeshes already created on contact onto new partition? That would be real time saver. Any help is appreciated. I attach salome 9.14 study here.[https://www.dropbox.com/scl/fi/o7ordots8auswvmuhx6a9/snap2forum.hdf?rlkey=zqo87s0t6jvmbpcqvpcyywv26&st=3nlbwcdf&dl=0]

Hi,
I’ve been fighting with workarounds for some time now and honestly, I haven’t found correct way to work with it without losing groups. I’m creating my geometry in separate program and import it to the GEOM module. When I make some changes I have to import it again. So when I do a geometrical compound or any additional work in GEOM I’m losing all the work and have to recreate the groups. I stopped using any GEOM feature except creating groups or sometimes orphan nodes.
What I recently discovered that works for me is omit the geometrical compound, create geometrical groups, create FEW SEPARATE meshes (they will contain the geometrical groups) Then create compound from meshes. That way you delete mesh compound and can work with geometry as you like.
Hi,
in the Partition dialog box, you can tick Set presentation parameters and sub-shapes from arguments. It will create groups based on input arguments with *from-" prefix. Untick Add prefix to names of restored sub-shapes to keep the same name without the prefix.
To re-apply the submeshes on the new shape, you can use Copy Mesh (from Mesh menu) with 2nd radio button. Set the new geom result as New geometry
