Hi Kossivi
Actually I have never used MRFSimpleFoam, so this is my guess.
I guess the rotation force might be added to N-S equation as a inertial force in MRFSimpleFoam.
Just imagine that you...

Yeah, I think so.
I guess you might have to monitor more long time for making sure it really become steady state.
If transient simulation become steady state, the monitoring value...

Actually, I have not set maxCo more than 10.
Simulation usually become in fail when I set maxCo more than 10.
But I've heard around 100 was OK from someone.
Generally simulation is...

If the python script is OK.
I will send you it.

Hi Kossivi
It seems to be very stable caluclation.
I guess there is no way except finding mesh where Co is high and re-meshing there.
Or,
increasing maxCo,
increasing parallel numbers.

I tried your case with interDyMFoam and found that the velociry became so high locally.
I think you have to modify the mesh.
To consider moving wall velocity, I also think around 1e-5 deltaT...

It seems that initial deltaT = 0.05 is the value of being set in controlDict.
How about trying to change the value of deltaT in controlDict.

Only water pass through with cyclic boundary
Hi
My problem has not be solved yet.
I am trying to customize fan boundary.
What I am doing is setting jump_ as -U*alpha, but jump_ seems scalarField and not being set vectorField.
