Restarting an unsteady simulation on a supercomputer

I've been running steady fluent jobs on a supercomputer for sometime now without any hassles. I use journal files for this purpose.
If my case is named as 'example.cas', the journal file commands I use to restart, run 10000 iterations and write files are like this: rcd example.cas solve/iterate 10000 wcd outfile.cas Now, for unsteady simulations, I've been able to start new cases and run unsteady simulations using the following commands: rc example.cas /solve/initialize/compute-defaults/pressure-far-field farfield solve/iterate 10 solve/dual-time-iterate 50 10000 What this does is basically initialize with farfield conditions and then run 50 time steps with 10000 iterations each. The problem I'm facing is that I want to run a further 20 more timesteps. But I've been unsuccessful in doing so. I tried running with the following commands in the journal file: rcd example.cas solve/iterate 10 solve/dual-time-iterate 20 10000 But it failed to run because fluent is looking for the file example.dat whereas the solution files for different time steps are numbered as example-00001.dat, example-00002.dat ..... upto example-00050.dat. If someone can help me in finding the appropriate command to make fluent understand that this is an unsteady case and I want it read the data from time step number 50, that'll really help me out. thanks in advance. |
