The case cannot create simulation because lost material

Hello,

My mesh was uploaded from constant.zip of openfoam. It has 4 volumes. I do not know why openfoam can easy assign material with 1 file. Simscale must choose every volume, and then it cannot create new simulation if I do only select 1 volume or 4 volumes.

Hi there!

I don’t think I totally understand the issue here. Can you please include a link to your project, and maybe some diagrams and further explanations of the issue? What is the expected results? What are you getting isntead?
