About the Advanced turbulent flux models in the code_saturne

Dear developer and users, I am working on using the advance turbulent flux models to simulate the buoyancy induced flow. I tried to use the ones implemented in the code_saturne. According to the 'user's guide', the 'generalized gradient hypothesis' (GGDH), 'algebraic flux model' (AFM) and 'different...

The prolem with convective outlet bounary condition

Dear developer and users. I am using the Code_Saturne 4.0.2 to run the FSI simulation to study the effect of the movement of the valve head on the flow field. The movement of the valve is defined in the usalcl.f90. To avoid the reflection from the outlet boundary, I created a convective outlet bound...

Re: Help needed on set a ALE simulation in Code_saturne4.0.2

Hi Martin, Thanks for your reply. I am have the moving mesh in the postprocess now. So i can investigate the simulation case a little more. I find the simulation come across the error (negative volume) just after several iteration as the ALE was turned on. I had tried you advise decreasing the displ...

Help needed on set a ALE simulation in Code_saturne4.0.2

Hello users, I am practising on using the ALE method to do the FSI via code_saturne. I genereated a 2d case which a movable cylinder in the channel. I defined the movemet of the cylinder in the subroutine usalcl.f90 and the mesh viscosity in the cs_user_physical_properties.f90. But shortly after the...

Re: Is it possible to record the pressure on the walls?

Hello Yvan, The final stage of my plan is eventually to using the two-way coupling. As a result, I am sure that I need the extra patches you mentioned. Thanks for your kindness, it will be quite helpful, if I can have them. I have some questions regarding coupling of code_saturne and SALOME_MECA. I ...

Re: Is it possible to record the pressure on the walls?

Hello Yvan, Thanks for your reply. It is greate that the code_saturne and code_aster can be coupled in the new releasing. To make the function work, what else do I need to do? Do I need to compile the code_saturne with code_aster(Salome-Meca)? Kindest regards, Yu. Hello, Do you expect to need coupli...

Re: Is it possible to record the pressure on the walls?

Hi Martin, Do you have any guidence for the coupling between Code_Saturne and Aster. If so, can you please share it with me? Thanks in advance, Yu. Hello, You can export the stress of the fluid on the structure directly in the GUI. The normal component is therefore the pressure (more or less). By th...

Re: Is it possible to record the pressure on the walls?

Hi Martin, Thanks for your reply. Unfortunately, I am using the subrountine to setup the case. As I can not install the GUI sucessfully. Can you please let me know how to do it via subrountines? Furthermore, it is realy great to know that the coupling is working now. I will try later on. Thanks very...

Is it possible to record the pressure on the walls?

Hello developers and users, I am using the Code_Saturne to monitoring the fluids structure interaction. The plan is using the code_saturne to obtain the pressure field on the boundary and apply it in the code_aster. I know that we can easily export the yplus and tplus on the wall in code_saturne 4.0...

Re: A question on restarting file

Hello Yvan, Actually I tried the method you suggested. however, I still have the same problem. I am wondering whether it is due to the subfuntion such as 'call field_get_val_s(ivarfl(ik), cvar_k)'. I guess it is to get the scaler or velocity field. I am wondering whether it is necessary to do so in ...
