Hi,
I am looking at the periodic BC with a rotation in a 2D flow. I managed to get NekMesh to work and align a PI-rotational boundary pair. I included a Rotated tag in the BOUNDARYCONDITIONS (it seems the tag is not used in 2D anyway), but what I get is not what I have expected. Consider attached figure, I have an outflow on top-right, rotated to bottom-right and I was expecting to see an inflow there.
I had a look at the DisConstField.ccp, and there is a small piece of code setting everything up (~4,5k lines of code), and from what I understand rotation is not accounted for in a 2D case.
My question is than:
1. Am I looking at the periodic-rotation BC in a wrong way?
2. Where are periodic BC enforced? I was unable to find the spot
where I could just plug a *-1 to reverse the flow.
Cheers,
Stan
