Hi,
I modified the code 'simpleIbFoam' for variable denisty and tried to run in an hpc.
It gives me the following error.('simpleIbFoam' runs without any issue).

Fatal error in MPI_Recv: Message truncated, error stack:
MPI_Recv(224).....................: MPI_Recv(buf=0x7ffdc2b6b720, count=24, MPI_PACKED, src=1, tag=1, MPI_COMM_WORLD, status=0x7ffdc2b6b6b0) failed
MPIDI_CH3U_Receive_data_found(131): Message from rank 1 and tag 1 truncated; 34368 bytes received but buffer size is 24

I tried

OptimisationSwitches
{
commsType nonBlocking;
}

and didn't work.
I went through Message truncated, error stack: MPIDI_CH3U_Receive_data_found

As instructed in there,I could not find a parallelTest.I'm using foam-extend/4.0

I appreciate if someone could help me.

Thanks,
Thamali
