Fluent Tui Command for transient
 

Hello All,

I have found the fluent tui guide somewhat difficult to use because it often tells you what a command does, but not the subsequent path to get there. I searched through this guide and have not found how to transition a simulation from steady state to transient. This is important for initializing when using the automated parameterization. Has anyone come across this?

Thanks in advance!

TUI code to set transient solver
 

;; To turn on unsteady first order
/define models unsteady-1st-order? yes

;; To turn on unsteady 2nd order
/define models unsteady-2nd-order? yes

;; To turn on steady-state solver
/define models steady? yes

;; To iterate with steady state solver (10 iterations)
(iterate 10)

;; To iterate with unsteady solver (10 time steps, with 20 maximum iterations per time step)
(physical-time-steps 10 20)

Hope this helps,

That is extremely helpful! Thank you very much. I am so very glad we have an active and helpful community

Where the hell does that come from? Ok, I found, scheme commands : http://www.polo.ufsc.br/~tiagom/docu...programing.pdf

For a reason that I ignore, the command 'dual-time-iterate' doesn't work when I open a transient case, load data and try to iterate further. Nothing happens. Is this a bug? Thanks.

Use
/solve/iterate 200
/solve/dual-time-iterate 200 20
instead. I have never been able to appreciate the merits of LISP.

Could you please tell how to write for setting pseudo transient case using TUI?
