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,

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...

Hello, Be careful with fixed-size arrays.... On may machine, I needed to switch to BFT_MALLOC to avoid memory errors (as fixed-size arrays are handled on the stack, and the corresponding size may be too limited vs dynamically allocated arrays. I attache the changed file (with paths also changed for ...

Hello, These arrays are "preprocessed" boundary condition codes (that are subject to a redesign in a future version), built from the icodcl/rcodcl arrays described in the user documentation. They match the a/b/af/bf coefficients described in the theoretical documentation's section on bound...

Hello, Your setup seems to be for v7.0. Could you try it in v8.0 ? Also, running the code in debug mode, I get a Fortran error in src/cogc/colecd.f90, line 607 (for v7.0), because iico2 is 0 (i.e. there is no CO2 variable), probably because the is no CO2 variable entry in your thermochemistry file. ...

Hello,

Yes. The idea If you are not familiar with a debugger, I can do a quick test on my side (it seems all the required files are in your archive). Just remind me which version of the code you are using.

Best regards,

Hello, I suspect a reinitialization, but am not sure where it happens. If you are familiar with using a debugger, putting a breakpoint in your user initialization, and putting a watchpoint on the first value of one of your initialized fields would certainly help find this quickly. Otherwise adding &...
