First off, I am using openFoam8.
This is to do a simulation using pimpleFoam to simulate a rotating boundary layer around a cylinder in order to produce the magnus effect.


My goal is to eventually incorporate this into a car simulation, in lieu of rotating meshes at the wheels, but I digress.


I modelled the cylinder in solidworks, and get a nice mesh with 2 boundary layers via snappyHexMesh. PotentialFoam runs okay. But when I run pimpleFoam, I get this error:

                         Create time
 

 Create mesh for time = 0

I read this as a problem with my 0/k file, and it is weird because nowhere in my code is "cyclicAMI." As a basis, I used the pimpleFoam tutorial for a propeller, but after many tries, as evidenced by the multiple // marks in the attached, still can't get it to work. My case files are included in the attached. Thanks again to all who have helped me in the past, and I hope that you might be able to do so once again.

It turns out that I have to be careful to put the #includeEtc "caseDicts/setConstraintTypes" line just after 'boundaryField' line, and not before, in each of the 0/* files.
This always seems to happen, that after trying hard to solve a problem and then giving up and bothering people for help, I find the answer. Not Murphy's law, but there must be a name for it.
But I will assuredly have more problems!
