Project: Basic Fan blade simulation
I attempted a simulation run for the fan, working of the online tutorials on how to simulate rotary machinery using the MRF rotating zone feature. Using Hex-dominant mesh to avoid the errors discussed previously in the forums to no avail, the cylinder that has the propeller was cleared out from the solid, and as of now it has 2 volumes those are:
-The rotating zone
-The flow domain
I could not understand why the simulation run is yielding this error

Hello!

Did you remember to create a cell zone within the hex-dominant mesh configuration? E.g. fig 9 from this article.
