Seeing 3D mesh as 2D surfaces

I performed mesh in my 3D geometry and when I use clipping tool, I cannot see the 3D mesh part, I see only 2D surface meshes.

I am not sure you can do that with the clipping tool, but under results (just run some empty/simple study) you can visualize the mesh and add filters to cut through it on a volume level.

Thank you for your reply, but I tried it. Still I cannot see the 3D meshes I only see 2D surfaces.

Are your sure you have not made a surface mesh on your domain then? Can you upload the file?

Cool. Make sure that you try first in post-processing to have 3D Plot Group->Mesh, change Level from Surface to Volume, and then right-click and choose Filter and x>0.1 or something. That should give you a cut into the mesh.

Yes, I tried filtering, still did not work. I am sending the file now.

To do what I suggest, you need to solve a Study. I put a some PDE/frequency study in there, and then in the results node you can see the volume mesh. Not sure if this can be done via the clipping feature without running a study, but you can ask COMSOL Support.

As I understand, a study is not necessary. Just right-click on Mesh 1 (after mesh build) and click 'Plot'.

Nice Greetings

Still I cannot see the 3D meshes I only see 2D surfaces.

Build the mesh, then right-click on the Mesh 1 node and click 'Plot'. A mesh-plot will be created. There reduce 'Shrink Elements' to 0.9 and add Transparency as subnode.

In Applications Libraries->COMSOL Multiphysics->Meshing Tutorials->bracket_swept_mesh is a nice example for seeing 3D Meshes. Mesh Plot 1 is prepared but mesh must be build before.
