A problem running fan sim

I am trying to run a simulation for a fan I am designing for a high school class a 50$ prize I want to test it out they just said make a fan just to learn the basics but I want the fifty so I’m going the extra step i have no experience with simulating things or simscale I have no idea what I’m doing I was watching videos and I can’t figure out what’s wrong it says " A setup with 3 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." if someone could help me I would appreciate it here is a link for the project SimScale

Hey there!

You need to delete the fan part from the model, after you create the flow region around it.
