Re: Internal Fluid-Thermal coupling with the V9.0

Hi SS2X,

Its going to be difficult to answer without seeing the case files (xml and user files), but normally you should have nothing to do.
If your mesh contains a sub-volume "SOLID1", by defining a volumic zone based on that subvolume, setting it to "solid" and checking the checkbox for thermal ...

Re: Internal Fluid-Thermal coupling with the V9.0

Hello,

Yes, by checking the box, you have an implicit coupling between the solid and fluid zones. Otherwise, you have two sub-volumes which do not communicate.

When using the "internal coupling", the energy equation is solved over the entire domain (all subvolumes) at once. The coupling is hence ...

Hi SS2X,

Normally it is. Is there a specific problem / difficulty ?

Re: Internal Fluid-Thermal coupling with the V9.0

Hi ,

I confirm that the snaphsot is not completely up to date, where "SYRTHES coupling" is now "CHT coupling", and should be changed in the documentation.

About your question and/or error, I think you may be mixing two different options in the code :

When selection "CHT coupling" (previously ...

Re: Utilisation MEDCoupling

Hello Bastringue,

Could you specify what you are trying to do with MEDCoupling and code_saturne ? code_saturne uses MEDCoupling for some functionnalities and usage can be seen in "cs_medcoupling_XXXX.cxx" files.

If you are trying to use a cartesian mesh within code_saturne you can generate it ...

Re: Problem rearding submitting job to cluster

Hi,

What version of code_saturne are you using ?
Normally if you are using a recent version (>= 6.0) you can use the "submit" command of code_saturne instead of the "run" command.
Typically, the "submit" command launches the python script on the login/frontal node and handles the creation of the ...

Re: Courant Number in NEPTUNE_CFD

Hi Florence,

The courant of fourier numbers were not handled as fields in neptune_cfd v6.0 (this is now done in v7), and the min/max were only computed on the fly during the time step evaluation process.
Hence if you wish to use any advanced postprocessing tools, you will have to compute the ...
