Hello Yvan, I have just installed version 5, it has two new fonctions, I would like to know whether the automatic scheme is better than the first order scheme, and if I use iterative process error estimators (with / without volume contribution), can i get a better convergence result? When I start to...

Hello Yvan, Here are the XML files, most of their settings are the same, only a small part is different. And the setting of the Periodic Boundary of my test model is wrong because it is a test. Another point, the biggest difference is that the mesh of the test model is very rough, and I do not have ...

Hello Yvan,

Thank you for your response, I will upload them Monday, thank you.

Could you remind me how to define time averages for postprocessing in Salome, I will be grateful.

Thank you very much

Hello Yvan,

You said which one? The model I had just calculated and didn't have heat exchange? I don't use user subroutines, so just file xml? I will upload it Monday.

Can it be considered as convergence, according to my monitoring points?

Thank you very much

Hello Matt,

I use the 4.0.6 version but not 5, but I think that at the beginning of the calculation check mesh will be automatically executed? Because I have never checked the mesh, but it has been in the RESU directory.

Hello Matt, I'am so sorry, in fact, I learned slome and code saturne less than two months, I do not even understand that User Manual, so I do not know how it is defined these pressures. But according to my previous experience, whether the fluid is moving or still, the pressure that we mentioned is s...

Hello Yvan, Sorry it's me again :oops: I have a problem with heat exchange, when I processed the results, I found that the model I had just calculated did not have heat exchange，but I have set the Exchange coefficient type and used the exchange coefficient of 50： non Exchange T.PNG And this is a mod...

Omega's stability is also very good: But the stability of K is poor: So I can think it is convergence?

The velocity of X, Z direction are very stable, but the stability of Y direction is not very good nor bad:
