Hey,

Is there a way to start the simulation with SIMPLE algorithm and then switch to Coupled Algorithm after certain time steps in an URANS simulation using TUI for a batch job?

Any help is highly appreciated.

LuckyTran has a spectacular aura aboutLuckyTran has a spectacular aura about
Just do solve/dual-time-iterate XXXX Y
where XXXX is some number of time-steps that you want and Y is the number of iterations per time-step

Then use the TUI commands to change the models.

You'll find them in /define/models
look for pressure-velocity coupling

Followed by another solve/dual-time-iterate XXXX Y

That's the most straightforward way.
