Running in batch mode and in GUI

hocon · July 23, 2019, 07:53

Hello,
My simulation is OK if it was run by ANSYS Fluent GUI. But if it was run by a batch mode on a cluster. The simulation was stopped after 400 time-steps as below . Do some one know how to fix it

Flow time = 1.898500084877014s, time step = 3797
15313 more time steps

Updating solution at time levels N and N-1.
