hello, I had write a script file for unsteady flow simulation. The script defines to read fluent *.cas and *.dat files, define the time-step size as 0.0001(seconds) and run a total number of 10000 time steps with a max 20 iterations per time step. The script is below,
/file/rcd zhu-20-2500-f01-rec.cas
/solve/set/time-step 0.0001
/solve/dual-time-iterate 1000 20
/file wcd zhu-20-2500-f01-rec-1.cas
/exit
y

but when I run it, the error will appear:

]nvalid command [

> /solve/set/time-step 0.0001

Error: eval: unbound variable
Error Object: 0.0001
Invalid time
time step (s) [0.0001]
Error: eval: unbound variable
Error Object: /solve/dual-time-iterate
/solve/dual-time-iterate Invalid time
1000 20
]nvalid command [20

How could I to correct the script? Thank you very much!

After reading the cas and dat files, is the simulation set to transient or steady?

It should be transient, but the warning you see might indicate it is set to steady. If that is the problem, you can solve it by clicking "transient" in the general tab, before you continue. I don't know the Text command to do this.
