Hi everybody,

I am facing a similar problem and I really cannot understand what is going wrong. I am using OpenFOAM 2.2.x. and I am trying to implement the PatchFlowRateInjection of OpenFOAM 2.4.x in my version of the code.
The code is working ok if I use the setPositionandCell member function of version 2.2.x. But when I try to use the patchInjectionBase::setPositionandCell of
OpenFOAM 2.4.x, which I 've manage to use with success in another injector I 've created without any errors,
the code, after running for some timeSteps, it suddenly crashes with the following error:
"Fatal error in MPI_Recv: Message truncated, error stack:
MPI_Recv(198)...........................: MPI_Recv(buf=0x7ffff2cf26c0, count=4, MPI_PACKED, src=0, tag=1, MPI_COMM_WORLD, status=0x7ffff2cf2650) failed
MPIDI_CH3_PktHandler_EagerShortSend(443): Message from rank 0 and tag 1 truncated; 8 bytes received but buffer size is 4".


The same code runs ok in serial. I notice that the problem occurs at
Pstream::scatter(areaFraction);
So one of the processors fails to receive the data from the master proc.
commsType is set to nonBlocking.

I would really appreciate any help on that.
Thanks, Pante
