How can I simulate a rc electric EDF?

Hey everyone,

I’m trying to run a simulation for my 70mm EDF. However, I’m not sure how to make it so that the air is actively drawn in by the EDF and accelerated out the back, just like in normal RC plane flight. Can anyone help me out with this? The link down bellow is the cad file of the edf. I cant find any good youtube tutorials, and AI like Chat gpt or gemini cant help that much too…

Thank you very much
