I used chtMulitRegionSimpleFoam in OpenFOAM-v2112, and found that whether the useImplicit is true or not has a significant impact on the results.
When the useImplicit was false, I got a higher temperature which is close to the result of Fluent.But when the useImplicit was true, I got a lower temperature.
The point is using Implicit spending less time than not using it, usually a dozen times faster.
1.Why does useImplicit have such a big impact on the results?
2.How to get more accurate results in less time?
