Dear friends

I have a problem in udf initializing problem in serial/parallel running in my PC.
when i running the udf in parallel the following error coming

C:\PROGRA~1\ANSYSI~1\v145\fluent\fluent14.5.0
tx86\3ddp\fl1450s.exe received fatal signal (ACCESS_VIOLATION)
1. Note exact events leading to error.
2. Save case/data under new name.
3. Exit program and restart to continue.
4. Report error to your distributor.
Error Object: #f

when i running the udf in parallel the following error coming

99999 (..\src\mpsystem.c@1172): mpt_read: failed: errno = 10054

999999: mpt_read: error: read failed trying to read 4 bytes: No such file or directory
MPI Application rank 0 exited before MPI_Finalize() with status -1073741819
The fl process could not be started.

so anybody help me regarding the above problem


I also posted my udf

#include "mem.h"

}
if ((m_lg == 0. ) && (T_v <= T_SAT))
{
m_lg = 0.1*vof_v*rho_v*fabs(T_SAT-T_v)*time/T_SAT;
}
return m_lg;
