I went through the whole (long) process of setting up my simulation twice and keep getting this message. I have no clue what the message means. I believed I was supposed to have two regions, a flow region and a rotating zone. Thanks. A setup with 2 regions is being used in a single-region analysis …

Hello @tzamani , For single-region analysis types, such as incompressible and convective heat transfer, you need a single volume representing the fluid domain to run the simulation. After generating the fluid domain, all solid parts (e.g. physical solid walls) must be deleted from the geometry. Fo…

Thanks but It’s just not clear. I still get this error : A multi-region mesh was assigned - this analysis-type requires a single-region mesh. I have an MRF zone and a flow zone. What analysis requires a single-region mesh? The error message is just too vague. SimScale Login Log in to…

CFD Squad, want to jump in here and give our user some tips? :slight_smile: Best, Jousef

Slowly, I started to figure it out, thanks.

Hey @mukwevhosl_rj ! There are plenty of questions regarding that particular message. You can use the search function to find some answers, I am sure you find something that applies to your case. Most likely you have more than one solid. The latest answer from my colleague and PowerUser @Retsam can…

You must make sure the geometry is one body. Fix it in your CAD program and then import it again.

I need help, I made a 3-d file using Paint 3d and converted it into an STL file them uploaded it to SimScale but it showed me the same error: A setup with 5 regions is being used in a single-region analysis type. Please make sure that all regions except for one have an Advanced Concept assigned to t…

Hi there @Robert01!

Maybe this thread here help: Question for Meshing and Volume
