code_saturne User's Forum

Thank you very much Yvan I will try that, I have also a little question about symmetries : sym1.JPG Is the previous picture equivalent to the following one ? (the dotted planes are the symmetry planes) sym2.JPG (just to ensure that code_saturne support those two symmetric planes as it should be math...

Hello everyone, Just a quick question about outgoing flow, I want to modelize a wind tunnel and my condition is an outgoing flow, how can I manage to do that ? Do I have to set the outlet as an inlet with a negative velocity and the inlet as a free inlet/outlet ? Moreover the incoming flux is heated...

Or maybe am I looking for the wrong convergence criteria ?
Can we assume convergence only with probes in the domain ?
Regards,

Quentin

Thank you Luciano, I can understand that I have not exactly the same behaviour cause the physic is not exactly the same ;). But speaking about convergence, do you have any idea why my norm. residuals are so high compared to the 10^-6 criteria ? Do I have to change something in my simulation paramete...

Here are the infos from my simulation :
CS : 4.0

I attached the files requested.

Hello everyone, I have some interrogations about convergence, i am trying to reproduce some results from an article (which gives HTC and temperature from a cube heated in an air flow) but the results I obtain are not really equivalent. Moreover my residuals are not in the usual range (under 10^-6). ...

Hi, Thank you xingjian, For the moment I will not be able to download the 5.0 release. So I try to deal with the norm. residual of the listing file, but the fact is that with an easy case (2D) I do not succeed to have residual under 10^-6 they are like stuck at 10^-4 (even when I switched from low r...

Hello,

I just come back to ask a new question (and not create another topic with the same title), I am wondering what is the Code_Saturne equivalent to the Fluent residuals ?
Is it the Rhs norm the Norm residual or the derive ?

Thank you,

Well I found my mistake, I add to my configure command the --with-mpi-lib, which give the following line : .configure --with-mpi --with-mpi-lib=/pathtothecorrectfolder/lib64 Then I got a lam libraries not found error, so I uninstalled lam/lam-dev (just keep openmpi and openmpi-devel). And tadaaaa it...

I found how mpi works, so I had to define in my .bashrc the following thing : export LD_LIBRARY_PATH=/<way to open mpi>/lib64:$LD_LIBRARY_PATH Because I had the libmpi.so.1 not found error, then mpi_hello_wold worked fine. When I run the ./configure I have the good parameters (such as hdf5 : yes, cg...
