Can anyone tell me how to solve this problem?
it is ok for a serial run,but it stops with segentation fault when i try to run parrallel in a cluster. my openfoam version is 2.1.1. Code:

Open MPI is currently operating in a condition that could result in memory corruption or other system errors; your MPI job may hang, crash, or produce silent data corruption. The use of fork() (or system() or other calls that create child processes) is strongly discouraged. The process that invoked fork was: Local host: node65 (PID 29186) MPI_COMM_WORLD rank: 4 If you are *absolutely sure* that your application will successfully and correctly survive a call to fork(), you may disable this warning by setting the mpi_warn_on_fork MCA parameter to 0. -------------------------------------------------------------------------- in
