Hello,

While reviewing results on the boundaries of my mesh, there is a "dimensionless_heat_flux" component. I could not find what its definition was in the documentation. Can anyone enlighten me?

Best regards

Hello, I have been able to investigate further and it's really weird. I pinpointed the problem being with trying to do operations with double and cs_real_t (I think). For example The code runs successfully if I write double dT_loc = T_loc; //Here T_loc is defined by cs_real_t T_loc = T[face_id] whic...

Hi Yvan, I switched to code_saturne V8.0 for simplicity as you suggested. The code now compiles but I get a SIGSEGV. I investigated the issue but I was unable to find what was wrong. Do you have any idea what might be wrong ? Best, Michael compile.log run_solver.log cs_user_boundary_conditions.c

Hello, I have tried running the simulation but bc_coeffs has no attribute rcodcl3. How do I do then to apply the Neumann boundary condition correctly ? EDIT : After investigation, it seems I should call the attribute af or bf, but I don't know which one I should call. Here is my code Best regards, M...

Thank you for your fast reply, Yvan.

Unfortunately, I cannot use the GUI because the flux depends on values of the properties of the liquid (such as viscosity, temperature itself, etc.) and are therefore not constant.

I will try it soon.

Best,

Michael

Hello, I am trying to use the cs_user_boundary_conditions.c user subroutine. But I am unsure if that should work, and I find the documentation very hard to read. Could you tell me if the following code should work ? /*============================================================================ * Use...

Great ! Thank you for your help

Hi,

Yes the z direction is normal to my boundary.
Does that mean I can just use the prescribed flux (user law) on this boundary? Since the z-axis is normal to my boundary

Best,

Hi, I am trying to find a way to implement a Neumann boundary condition on the temperature T in the z direction only. Via the GUI, I can use the "prescribed flux (user law)" to define my function but I don't know how I can define my condition. Essentially I am trying to impose the conditio...

Hi, I am following the "full domain" tutorial. More specifically, the first case. When I arrive at the computation stage. I get the following error displayed : code_saturne ============ Version: 7.0.6-patch Path: /home/fuxin/Code_Saturne/7.0.6-patch/code_saturne-7.0.6-patch/arch/Linux_x86_...
