First of all, I also tried with a coarser mesh. It was ok in checkMesh, but it stilled crashed with the following error:

I played around with the parameters in fvSolution for this one with no success.
About the number of cores you are right, it is too many. But anyway it has been running way faster with 128 than with 8 cores. I heard before that there should be around 50k cells for each core, so 20 could be a good number of cores.
I am trying to initialize with potentialFoam by adding these lines to fvSolutions:
Code:
potentialFlow
{
nNonOrthogonalCorrectors 10;
}
How can I use LTSInterFoam to initialize? The quantities are quite large as you say, inlet speed of almost 40 ms1 and quick rotation.
