Hello, everyone! Recently, I encounter some problems when install code_saturen 5.0-beta on the cluster. I have install this version on my personal PC and any problems do not appeared during installation and case simulations. But, some problems appear when install on the cluster. (1) Problem one: How...

Hello Yvan, Thank you for your reply. Follow your advice, I do some modification and upload the new result. First, I generate a little more coarse mesh from Salome 7.8.0 by myself. The mesh from NASA website is not used for this case because its too finest. The location H=-4 is the inlet of the back...

Hello, everyone Recently, I use code_saturne 3.0.7 to simulate backward facing step flow. The Reynold nember is about 36000 base on the height of the step. The more information can be found in NASA turbulent model website(https://turbmodels.larc.nasa.gov/backstep_val_sst.html). The turbulent model u...

Hello,

Now I have a new question about restart calculation. As I add an user solver into software, so can anybody give me some ideas about how to output some variables which software do not need to solve it. And this method can adapt to do parallel computing.

Thank you.

Best regards.

Hello, I find a phenomenon. Although have good distribution of turbulent viscosity if I set turbulent intensity equate to 0.001, it will have a waring from Python, like turbulent intensity must not be neither negative neither 0. If I set 0.01, though have any waring, but have little oscillation. Bes...

Hello, Yvan I am sorry to disturb you again. In the last three months, I prepared the exam, and delayed my work. Recently I continue to simulate 2D turbulent flat plate(use SST model). As your suggestion, I generate a new mesh, and have any waring about y+ in the listing. And reduce time step, it wo...

I'm sorry I forget to tell somebody who can help me something. The version which I used is 3.0.5. And I do not use user subroutine in case. If some other files will help to solver the problem, please tell me then I will upload.

Thank Yvan very much! Here I upload the cases which set up in Code_saturne. Inculde mesh, xml file, schematic of flat plate, and two post-process files. a. In picture of schematic, as In GUI have no farfield boundary condition, I also set as outlet boundary condition; b. xml file. I set two Reynoly ...

Thank Yvan for your reply! I'm a postgraduate from Northwestern Polytechnical University, China. Our research direction is lattice Boltzmann method(LBM). Since last September, I interested in Finite Volume LBM(FVLBM), and finial choose Code_saturne as a develop platform. In the program, we don't mod...

Hello, everyone: I'm a newer in Code_saturne. Recently I want to simulate a case that 2D turbulent flat plate. The Re is 5 miilon and the mesh is download form NASA Turbulence Modeling Resource(http://turbmodels.larc.nasa.gov/). The RANS model which I used is S-A turbulent model. I have some questio...
