Hi community,
I am running one simulation with dynamic mesh, where I am defining the motion by grid motion udf. In that I have done parallelization also . I am running simulation on Linux machine and I am facing following error Fatal error in MPI_Recv: Message truncated, error stack: MPI_Recv(224).....................: MPI_Recv(buf=0x3453bce0, count=6160, MPI_BYTE, src=0, tag=0, comm=0x84000002, status=0x7ffd966ed2a0) failed MPIDI_CH3U_Receive_data_found(131): Message from rank 0 and tag 0 truncated; 6256 bytes received but buffer size is 6160 The fluent process could not be started. Simulation get stops and throws this error. Can someone please help me out to understand the source of the error and How can I tackle this. |
