Segregated vs Coupled solvers
 

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

Any thoughts??

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.
