Hello World.
I tried to run an interDyMFoam case in parallel. I first run the decomposePar and split the domain into two. After running mpirun -np 2 interDyMFoam -parallel >log there is this entry in the log-file: DICPCG: Solving for pcorr, Initial residual = 0, Final residual = 0, No Iterations 0 [0] #0 Foam::error::printStack(Foam:: Ostream&) and still one processor is running interDyMFoam. What went wrong? BTW I'm using a 64bit machine.

Meanwhile I got the solver to work on two processors, but the computational time is the same as with one processor.
Although the two processors were busy the corresponding processor-directories are empty and the main directory is filled with the final solution directories. I think there is something wrong, but I have no idea what it may be. Maybe I made a mistake splitting the domain (which is containing a cyclic bc)? decomposeParDict
