Hello George, I am not sure what specific change in 2.2 helped with SALOME, unless you are using environment modules on your system (in which case the environment modules supper test in 2.2.1 could cause issues). In any case, it is good to know that it works (as version 2.1 is not a long-term suppor...

Hello, If you do not need anything more advanced than what is available using the GUI, why do you need user subroutines (unless you want simultaneous MED and EnSight output) ? If you only need an additional mesh or sub-mesh or output format with the same variables, you only need to use usdpst (check...

Hello, Code_Saturne only uses 3D meshes. For an axisymetric case, you need to extrude your surface mesh by rotation along its axis of symmetry, so as to obtain a mesh at least 1 cell thick; so you can use any axis you want. For faces on the "base" or "extruded" base of the mesh, ...

Hello,

Yes, I often build "groups from geometry". To do this, I usually need to use "new entity -> explode" to build sub elements (i.e. surfaces for a volume) first, and build groups on those.

Hello, SYRTHES uses a transparent radiation model, but to couple it with Code_Saturne, you need an associated solid domain. Code_Saturne's radiative model is semi-transparent. Did you try using a temperature in Kelvin instead ? Otherwise, please follow the forum usage recommendations, as there is ot...

Hello, There are very few examples for this, but I attach a setup (using version 2.0) of the "ECHO" test case, which uses a mix of Helium and CO2. In that case, inlets are separate, but this is not essential to the setup. I will try to add a case description by tomorrow. To define a surfac...

Hello, Actually, CDTVAR is defined in a global Fortran array which is not directly accessible from the C part of the code, so there is no easy way to do this now (except hard-coding the same value in cs_coupling.c than the one you set in the GUI for the scalar). With the new C "fields" API...

Hello, You may find more help regarding SALOME on the SALOME forum (http://www.salome-platform.org), but to build an "IJK" hexahedral mesh on a cylinder, you will need to subdivide it into several pieced and build an "O-grid" (I don't have an image immediately available, but you ...

Hello, Although using the same value as that of CDTVAR is very easy for you to do on a given case, using CDTVAR automatically would make the coupling difficult to extend, as I mentioned earlier: for example, if one Code_Saturne instance (using RANS) were coupled both to SYRTHES and to another Code_S...

Hello,

IPHYDR is the keyword for the "improved" option of "pressure interpolation in stratified flow", so you must use the "standard" option.

Best regards,
