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. |

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. |
