Hi @simscale7yahoo!
The simulation you are referring to has converged. Some remarks from my side:
- Why do you choose the bottom wall to be no-slip?
You can use two custom boundary conditions with one defining the BC of the propeller and the other one the bounding boxes. An example can be found here: Propeller AMI.
- The velocity you put in is not going through the propeller as it should
It should be the negative x-direction and you have defined the geometry to be stationary so far. I do not think that using a moving wall velocity of the bounding box is a good substitute for the AMI/MRF approach. So you should consider working with that. That’s why you have probably opened up another post.
Cheers,
Jousef
