Default Error in parallel computing

Hi,

I am running a cas/dat file on 8 compute nodes without using GUI. I got error information such like:

reversed flow in 1682 faces on pressure-outlet 18. turbulent viscosity limited to viscosity ratio of 1.000000e+05 in 53820 cells

Error: > (greater-than): invalid argument [2]: wrong type [not a number] Error Object: inf

# invalid command [#] max number of iterations

Warning: An error or interrupt occurred while reading the journal file. Some commands may not have been completed.

> Halting due to end of file on input.

However, if I use GUI to run the model, there is no such problem.

What is the reason for the error? Is it due to the partition of grid? By the way, I use the auto-partition.

Thank you in advance.
