Number of regions error

Project Support
1

Hello,
I’m new on Simscale. I would like to model the smoke flow during a fire in a tunnel. For the moment, I would like to try without ventilation systems. I created my geometry on Solidworks. I followed the steps of the car park tutorial, but when I want to run a simulation I still have an error : “A setup with 2 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” but I don’t know how to solve it.
Here is my project : Essai apres prise en main | SimScale
Thank you for your help.

Hey there!

The source of the error is that you kept your box and enclosing parts in the model, when only the flow region should remain for the simulation:

You can use the Body - Delete operation in the CAD Edit mode to get rid of the additional parts.
