Multi region mesh error during a CFD simulation

Project Support
1

Hello!
I am trying to run a CFD simulation of an F1S car. I have created the mesh for it (I roughly followed this tutorial Aerodynamic Flow Behavior Around a Vehicle Tutorial | SimScale)

After completing the mesh, I tried to run a simulation but it showed up with this as an error:

Hi there, thank you for sharing!

The thing here is that you have two additional parts (the two wheels).

In order to resolve this, please enter the CAD mode, and delete these bodies, like you can see in Figure 9 & 10 in the tutorial. :smiley:

Hello!

I see where I have gone wrong.

I would need to recreate the mesh and redo the other components after this correct?

Hello all ,
I have the same problem but my simulation should have two parts , rotor (which have the blades inside) it will be rotating using MRF, and the flow domain which will be moving air with inlet and outlet boundary conditions. So my simulation require two parts what should it do .
my project :

THANKS

Hi, you can remove the blades from the flow region in the CAD mode. There is a dedicated feature called ‘Delete’ for bodies. Use the blades as the tool and the flow region as the target.

Best regards,

there is no blades it is a cavity inside the rotor part
