MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.

mpirun has exited due to process rank 0 with PID 1873 on
node thesis-X58A-UD7 exiting without calling "finalize". This may
have caused other processes in the application to be

In case you missed it, the iteration terminated because the number of iterations for time step in temperature calculation exceeded maximum limit (default defined as 100/time step). Usually this can be fixed by choosing an appropriate boundary condition, or, sometimes, changing the time step size.

thank you dear traib.but how did you find that the error is because of temperature?e has only 3 iterations at the last iteration.thanks.

Temperature is obtained from energy value after energy calculation using energy-temperature inversion method. Check src/thermophysicalFunctions/specie/thermo/specieThermo.H to see how this works.
