Hello,

Many thanks for the bug report. It is now fixed on master, 6.2, 6.1, 6.0 and 5.0 branches.

Best regards,
Erwan

Hello Rodion, Thank you for the description. Looking at the model, my first remark is that unlike the model described in this old thread https://www.code-saturne.org/forum/viewtopic.php?f=4&t=1917 that you mentioned, the added term does not write as: div( phi C u_r ) with u_r a vector, and C a g...

Hello,

To be able to give more adapted advices:
can you give some description of how this vector A is computed ?
what does this term stand for, or what phenomena is it modeling ?

Thanks,
Erwan

Hello Daniele, Through the GUI, you're correct you have to select the standard (incompressible) model. Then in 6.0, you've got the possibility to enable a Boussinesq approach by setting in cs_user_parameters.c, idilat=0 (dans la structure stokes_model, voir exemple dans doc Doxygen); then you fill i...

Hello,

Apparently, hdf5 was found by configure.
Could you please post the preprocessor.log you mentioned in an earlier post ?

Cheers,
Erwan

Hello Alessandro, Sorry for the late answer. In the VoF model, as implemented in CS, the assumption that density varies linearly with the void fraction is used to derive the void fraction equation from mass balance and mass balance itself is solved under its incompressible form i.e.: div( \vect{u} )...

Hi Konstantin, Launder-Sharma is a low Reynolds turbulence model, so using it to take into account rough walls with a wall model does not make much sense. Nonetheless since the title of your thread calls for a more generic answer that might be needed by other users as well, you can find a user examp...

Hi,

you can take a look at section 2.1.4 of the theory guide for the definition of the solved pressure p*.

Hoping you'll find useful elements there,

Regards,
Erwan.

Nice geometry by the way !

Hello, The exchange coefficient is computed using a harmonic mean of a left and right diffusion coefficient. On fluid side, the coefficient is seeing the turbulent wall model. Is the second test case (square) laminar ? Could you send me this test case as you set it ? It's hard to answer your second ...
