Error while starting the simulation

i am getting this error - A setup with 90 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 them.
Can u please help me

Hi @lbhati ,

Please make sure to link the project in the thread, otherwise we can’t see what you are trying to achieve.

Generally speaking, unless you are running conjugate heat transfer simulations, you should have a single volume (i.e. the flow region) for your simulation. The solid parts (e.g. walls) are not required and should be deleted --It’s a good idea to check out some of the tutorials before running your studies.

For example, the “CAD mode” section from this tutorial should show you more details: Aerodynamic Flow Behavior Around a Vehicle Tutorial | SimScale
