Segregated vs Coupled solvers

Bal · March 30, 2022, 06:47

Hi All,

I'm running a simulation using segregated solvers and it converged. However, when I switch to coupled solvers, it diverged.

What are your suggestions?

Thanks,
Bal

Do you have access to the Support Portal? There are several articles with tips how to use the coupled solver, for example https://support.sw.siemens.com/knowl...00039862_EN_US
The user guide also has a chapter on it, try searching for "Coupled Flow Guidelines". If that won't help, try posting more details about your problem.
