Hello, In the development version, there are quite a few optional fields than can be used to save various intermediate terms in the RSM solution, which might be useful for this (see src/turb/cs_turbulence_rij.cpp). Some elements of associated field names may be given in the Doxygen/HTML documentatio...

Hello, You can increase the number of time steps saved in a given field by using cs_field_set_n_time_vals for all fields where you need this, but if you keep too many values, the memory use may go up quite fast.. For each associated time, field->vals points to the values associated with time step n-...

Hello, In ALE, the mesh deformation is not stored in the mesh_output, but in the auxiliary restart file. So what you need in this case is to restart from a different mesh, in which case the deformation from the first case will be interpolated to the new one. You may want to reset other fields to 0 i...

Hello,

Thanks for the detailed report. I have a very busy week ahead but I'll try to look into this as soon as possible, probably end of next week or early week after.

Best regards,

Hello, Do you have a small test case where in.1), the temperature does not seem to change ? Another user reported something similar (bu I have no.details) so I need to check whether this is a subtle case setup issue or whether we may have a bug here. To see the effect of radiation on.the wall, I thi...

Hello, The tutorials by Cyprien are rapidly becoming obsolete, are were done independently of the code_saturne team, so are in no way updated by us. The real install documentation is the one in the code sources, even if it is a bit minimalist. With newer installs of the salome_cfd_extensions, there ...

Hello,

Did you do the post-install part of the code_saturne setup (i.e. editing the code_saturne.cfg file in the installation directory) ? Looks like this is missing, based on your error message.

Best regards,

Yvan

Hello, If this should converge to a steady-state solution, the time steps do not need to be identical between the fluid and solid domains. In this case, I would recommend the pseudo-steady algorithm on the code_saturne side (with a local time step), as this will optimize for the CFL number and usual...

Hello, I'm not sure how you could force a pressure at a given point with no outlets using the current code options, and am not sure it would help (since normally things depend on the pressure gradient but unless you have physical quantities depending on pressure, there should be no influence). I any...

Hello, The error simply reports the line in the source code relative to where the error is caught or handled, so as to help with debugging and analyzing the issue, so the message you obtain is normal. You now need to understand why the mesh input file was not found. Either the tutorial links directl...
