Re: Conjugate heat transfer of simple geometries - comparison with exp data
Second topic, I want to use the frozen velocity field at 150 degC to start a transient simulation for heating the steel cylinder inside the fluid volume. I see that there is an option where I can restart the simulation since a checkpoint + option the have a frozen dynamic. I try this but I don't hav...

Re: Conjugate heat transfer of simple geometries - comparison with exp data
Hello, I have first cases. kwSST with y+ around 1 (all y+ option) in stationary simulation with conservative parameters. I obtain some results but the convergence is not achieved. I use monitoring and see that the values are constants after 400 iterations. See the convergence image attached. I run t...

Re: Convergence tool
Hello, I have delete all the code_saturne folders in my $HOME. I have restart from the beginning the installation with "install_saturne.py" (the only way I can manage to install CS...) I have still the error... Do I need to uninstall CS with a command line. I have installation files referr...

Re: Convergence tool
Hello, I am sorry for the stupid question again, but I don't succeed to do this. I run in my build directory. $ ../code_saturne-7.2.0/configure $ make $ make install make install need to be done with high permission level is it normal ? The re-install takes several minutes but in the GUI convergence...

Re: Conjugate heat transfer of simple geometries - comparison with exp data
Hello,
Thank you for your answer.
Someone else have some experience with conjugate heat transfert with CS?
I know that it could be a long fight to find the right parameters.
I could start with SST y+1-5.
Best regards
Julien

Re: Conjugate heat transfer of simple geometries - comparison with exp data
Hello, Thank you for your answer. Could you tell me what is the best turbulence model to capture heat transfert exchange ? Low Re models are always recommanded but heavy. Re numbers are between 5000 to 50000 In Openfoam a good choice was kwSST with y+ around 30 associated with the right wall Law. 2e...
