Re: Flow module
Hi Johann, This warning shows the largest error (in this case of the continuity equation) between two intermediate outputs. If this warning only occurs during the first iteration, or in a few iterations at the start while improving, it's not a big concern. It just indicates that the criterion was no...

Re: The temperature calculation coupled with flow wheather consider the convective heat transfer
Hello Shenyz, as Bernd already wrote advective heat transfer is currently not implemented in MICRESS. To tweak performance of the flow solver please see section 4.15: Using the Flow solver in Vol 2: Running MICRESS from the MICRESS manuals. Specifically subsections 4.15.4 to 4.15.6 discuss the meani...
