Re: ALE - mesh viscosity in v6.0
Hello Yvan, I have checked the error.case, and the problem is actually the mouving boundary condition, set as "internal coupling". If I change it to "fixed velocity", the simulation runs fine. It looks strange, as if "internal coupling" of the GUI was not recognized. Is...

Re: ALE - mesh viscosity in v6.0
Dear Yvan, Thank you for your help. I figured out that the problem was simply a wrong link not deleted to the v5, there was therefore an incompatibility. Nevertheless, I still have issues in setting up my ALE simulation in v6. I followed step by step the setup I had in v5, but it seems that I have a...

ALE - mesh viscosity in v6.0
Hello, I have recently upgraded to v6. I have problems in correctly defining the mesh viscosity through the "new" subroutine usvima. I select "isotropic" Inside the GUI. I am using the default usvima inside the cs_user_physical_properties.f90 of v6, where I have just added the va...

Re: ALE simulations: local fluid force on specific rigid body positions
Hello,
Thank you for your help. I don't want to get the force on the Y direction, but to create N points along Y (of the rigid body), where to monitor X and Z forces...
Hope my question is clearer now...
Thank you very much.
Regards,
Daniele

ALE simulations: local fluid force on specific rigid body positions
Hello, When performing ALE simulations with the internal coupling for rigid body/mesh displacement computation, fluid forces are monitored during the simulation. I guess the default printed value represents the integral of the fluid forces along the i-direction on the rigid body. Is there a way of m...

Momentum source term treatment in porous media
Hello,
I would like to know if code_Saturne "automatically" multiplies the momentum source term by the porosity inside a porous domain, or if I have to explicitly include the porosity multiplication Inside the cs_user_source_term.f90.
Thanks a lot in advance.
Best regards,
Daniele

Re: probe of maximum y+ on wall
Dear Yvan, Thank you for your help. Actually, I am just trying to output the maximum y+ value on a wall during the simulation, in order to check if it is lower than 1, for instance. I would like to have something like a two column file, with one column being the time and the other the y+ value, for ...

probe of maximum y+ on wall
Hello,
Could anybody give me a hint on how to create a probe showing the maximum y+ value on a wall boundary condition, during a simulation?
Thank you very much in advance.

Implicit coupling convergence in ALE simulations
Hello, I am trying to evaluate the difference in the results between a one-way and a two-way coupled FSI simulation. For the two-way coupling, I am fixing a "Maximum number of sub-iterations for implicit coupling with internal structures" greater than 1 and the "Relative precision for...

Re: ALE calculation suddenly stopping with no error
Dear Luciano, Thank you very much for your help. Actually, looking more in detail to the listing, I found the message "Abort due to the detection of a negative control volume.". Do you know how to visualize negative volumes in Paraview? I cannot manage to do it. Thank you very much in adva...
