How to import .msh mesh and edit it in ICEM?
 

Hi everybody

I have fluent mesh (.msh) that I have successfully imported to ICEM. Now I want to edit it, more specifically I want to change the resolution/lower the number of nodes. I can't find a way to do this as the blocking tab is not accessible(it is shaded grey). Any suggestions?

Thanks

You can't do that, you don't have the geometry, the mesh is already generated. The only thing you can do is to modify it in the mesh tab. you can refine, translate and many more...

What if I created the mesh in a different Workbench and want to edit this mesh in a different Workbench Project?


When I try this I have the same problem as Wizze.



Thanks a lot!

Ali is right; you can only edit a mesh file with the predefined mesh tab in ICEM.

Well if you have the system geometry file as well, you can obviously change / edit the mesh in the different Workbench project. If you want to edit a mesh from a mesh file (.msh / .uns) in ICEM you just have the mesh tab option. If it’s a “minor” edit, say change some node alignment / position / symmetries you could manage with those tools, but if you want to completely change the mesh topology it doesn’t make sense to start from the mesh.

In case you ended up with only a mesh file without the source geometry, you can still regenerate the geometry from a mesh file (can cause some feature loss) and then remesh.

With the new workbench releases, starting from 2019R2 (if I remember correctly), you can also directly export a ICEM .prj including the .tin geometry file and .uns (File > Export > Mesh > ICEM) which will allow you much more flexibility.

Have fun ;)

The easiest way to do it, without the source geometry, is to use the option Mesh->Facets in ICEM. This will create geometry entities with some loss of detail, as stated above, depending on the complexity of your domain. You can then remesh.
