Hello Yvan,
I have implemented inside the extra_operation.c function, but I will prepare a small test case with the gradient reconstruction using this equation and I will share for your analysis.
Regards,
Luciano

Re: Cell gradient reconstruction
Hello Yvan, thanks for your answer. Yes, both lead to the same issue. In discussions with colleagues at the institute, two options emerged...one was to obtain the potential face value using the fluxes and then compute the gradients based on this face value and the local conductivity. This option wor...

Cell gradient reconstruction
Hello, I am facing a problem when computing the gradient of a scalar field with a variable physical property (conductivity) in the domain. Using the cs_field_gradient_scalar() I can compute the correct gradient in the domain, but in the cells in the interface between different properties, where a di...

Re: restart problems with v7
Hello, I have faced the same issue as you in one of our clusters with CS 6. I think that the problem is during the writing of the restart files. The solution that I found was to change the input/output method, from default to serial I/O. Captura de pantalla de 2021-12-09 09-16-31.png Regards, Luciano

Re: ALE method and Internal Coupling Problem
Hello,
In order to solve a FSI simulation, you have to couple Code Saturne(fluid-mesh movement) and Code Aster(Solid). This coupling (by the moment) is not straightforward.

Re: ALE method and Internal Coupling Problem
Hello, Do you need to solve a fluid-structure interaction problem? or Will you impose de mesh deformation? The Internal Coupling option does not solve the elasticity equations. Also, you can post the log file in order to help you with the error. Please check the Code_Saturne usage forum guidelines p...

Re: How should i do to set the boundary conditions by python scripts
Hello, The difference between solutions is because you are running two different cases. Please check the definition of the norm of a vector( ||\mathbf v||=\sqrt{x^2+y^2+z^2} ). When you use the GUI the norm is set to 3 m/s (vx=vy=vz=0.707m/s) and when you use the user define function you are setting...

Re: How should i do to set the boundary conditions by python scripts
Hello, I had used the specified coordinates, but I am so confuse about this set. maybe when I set the coordinates x=1, y=-1, z=1, it means that the coordinate is like the picture ? and the coordinate x=3, y=-3, z=3 is equal to the x=1, y=-1, z=1 ? or 3 is the unit length? You have to set the norm of...

Re: How should i do to set the boundary conditions by python scripts
Hello, Recently I want to use python scripts to set the boundary conditions. but when I simulate the simple case, I saw the result is not my want. The code that you post uses Fortran, not python. I didn't find the v and w direction set in GUI To set the x,y,z directions for the velocity in the GUI y...
