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)?
