[Gmsh] Load a partial mesh into Gmsh

[Zenker, Dr. Matthias]

You may also try to mesh all the rest, load just the mesh (without the geometry), merge the geometry for the heat sink and remesh . The only problem could indeed be at the interface. Maybe you could try to have the interface already meshed, remove volume and interface from the heat sink geometry, and rebuild the volume of the heat sink using the meshed interface.
I didn't test it myself, though.

HTH,

Matthias

Hi Tibi,

How about meshing all the components individually and saving the meshes, meshing the heatsink by itself and then  combining all the meshes into the final one?
It seems to me that the only difficulty is to match the meshes on the interface (hopefully, only one face).

Regards,
Serban

Subject: [Gmsh] Load a partial mesh into Gmsh

I'm working on a system that simulates a family of components; these components are fixed (as in modeled once, and then re-used again and again), but the heatsinks attached to them are user-defined. Gmsh takes a long time to mesh this system, so I'd like to cut down the time used for meshing. I was wondering whether it's possible to use Gmsh as follows:
- Pre-mesh each of the components and save these meshes
- Then, when meshing the entire system (a component + an user-defined heatsink), Gmsh loads the mesh for the component, and meshes only the heatsink.

Is this possible to do? I've seen some mentioning of "background mesh" in the documentation, but there is very little on that, and it's not clear whether it does what I'd like or how to define it.

Any hint/help is really appreciated.
Tibi Chelcea
