Match mesh on opposed surfaces?

[Zigmhount]

Hello all,

I'm looking for a method to connect the meshes of two solids through one or more coincident, opposed surfaces. These surfaces aren't simple or mappable surfaces and the solids are with tet elements modelled.

- Merging the solids wouldn't be handy since I need the contact surfaces, and both solids could be of differents materials.
- The "glued connection" tool is very convenient, but in some cases there are singularities, I assume because of the force interpolations between the nodes of both surfaces.
- Then I can try to make the meshes match each other by:
* projecting curves on surfaces to get identical surfaces ;
* setting same "mesh size on surfaces" ;
* setting "custom size along curve" to match the previous meshed edge ;
* setting "approach on surface" to link the meshes of both surfaces ;
* and finally mesh the coincident nodes...

Is there anything faster??
Thanks for your help.

Hello Zigmhount,

did you try the option geometry > solid > intersect.

It will break surfaces of solids a their common intersections.

And then,mesh the solids separately. For me it works.

Then you can merge coincident nodes with tools > check

Thanks nicolas, I'll try this out. seems a lot better than projecting every curve

I also found out that setting the mesh size on 2 identical contiguous surfaces which *do not have any attributes yet* automatically links one surface to the other - however I can only use that when none of the solids are already meshed. For smaller models it's a good option to remesh all of the considered solids.
