I have been running Fluent jobs in the background (batch). The input file I have used has the form:

rc x.cas (reading the case file)

rd x.dat (reading the data file)

it 1000 (1000 iterations)

wd x1.dat (writing data)

.

.

.

.

etc.

This input file was for steady state cases. I'm trying to run unsteady cases now. Do I need to make any changes to the input file ? I don't see any indication of an unsteady case running, though the case has unsteady solver specifications and a time step setting. I need to run the jobs in the background and can't run them interactively (nice value is higher for interactive jobs on the SGI machine I run the cases).

Hi,

You should add another step to run unsteady in the backgroud.

For example, add solve/set/

solve/dt/ in your input file.

Good luck,
