Hi everyone,

I’m facing an issue with the visualization of my solid geometry in CST Studio Suite  . I created a solid cube using the "Create a Box" command and applied the correct material (concrete). However, when I run the simulation and use the Cut Plane, the cube appears hollow in the results. I only see the outlines of the cube, and the inside seems empty, even though the geometry is solid in the model.

When using the Cut Plane during the modeling phase, the cube appears solid.

What I’ve already tried:

• Disabled Wireframe
• Checked the mesh — it looks fine
• Reset visualization settings and tested various view options

Any suggestions on how to fix this issue so that CST displays the geometry correctly in the simulation results?

Thanks in advance for your help!
