setting up multiple runs
 
Hi all,

I have searched but I can't seem find anything relevant to my problem. Basically, I have set up a flow system (channels within a substrate) I have then set-up an inlet velocity and an out flow. The system runs fine, which is always great, however, I want to change the inlet velocity and produce a graph of velocity against temp (there is a heater attached to this system). Does anyone know how I can do this, without having to manually change the inlet velocity and run the iteration again?

Switch to unsteady solver, and create a profile for your velocity inlet.
Or you can create a batch file, with something like:

rcd case1.cas
yes
it 1000
wcd case1.dat
yes

rcd case1.cas
yes
define/bc/velocity-inlet (check help for setting it with text command)
it 1000
wcd case2.dat
yes

etc...
