HFSS error: Please check properties of material: patch

[aabdullah]

I'm trying to build an antenna for my final year project but I'm getting the following error when I click on 'Analyze all':

HFSS Port Refinement, process hf3d error: Failure in setting up materials: Please check properties of material: patch.

BTW 'patch' is just the name I assigned for the 'draw box' object I used for the patch of the antenna I'm working towards simulating. When I look at the properties of the 'patch' material, I can't seem to see anything wrong...

I belive that it is due to corrupted geometry.I would create a regular standard patch antenna and try again. If the problem does not appear it means that your current antenna casuses the problem and you probably should re-create it.
Another option is that your ports are not assigned well. How many of them you have in your design? If you have more than 1, you should identify which of them casues the problem.
