Errors when using materials different than itu_concrete

[paulalmasan]

Hi, I'm loading a scene to sionna where the buildings have the "itu_concrete" material and the ground is set to "itu_medium_dry_ground". When I'm executing the load_scene() the preview works properly and I can visualize the scene. However, when I'm executing "cm = scene.coverage_map(cm_cell_size=[1,1])" I'm getting the following error:

If I change the material to "itu_concrete" it does work well. I've tried other materials and it only worked when the ground is set to "itu_concrete". Actually, when I try "itu_metal" or "itu_brick" the jupyter kernel dies when loading the scene with load_scene() and I can't even see the preview.

Hi,

The issue is that not all ITU materials are defined for the same frequencies (see the Table in the API documentation of RadioMaterials. So you would either need to change the frequency or choose a material that is defined for your frequency of interest. You can also create custom material if you want.

However, the fact that the kernel dies is undesired behaviour that we need to investigate.

Hi @paulalmasan,

Could you please provide a code snippet that reproduces the error?
