Re: free surface not moving

Hello, Thanks Luciano for your precious help! Seems we are close to solving the problem now. From my understanding of the user guide, the "ialtyb" keyword is also relevant for boundary condition associated to mesh velocity, and can take as well the "ifresf" (=free surface) value....

Re: free surface not moving

Hi Luciano, Yes, next time I will post the updated subroutine, sorry about that. By "digging into" I simply meant that I tried to understand how and where the free surface boundary condition was treated in the src. I wanted as well to install a debugging version to check why the mesh veloc...

Re: free surface not moving

Hi Luciano, Thanks for your post. I agree with the 3 items you have mentionned - there were mistakes in my initially posted user subroutine. I already fixed it as well some time ago; I could have uploaded the updated subroutine, but since it does not change the fact that the free surface does not mo...

Re: free surface not moving

Hi Yvan, Sorry for late reply. Still working on this topic :) First of all thanks for the interesting example, which is unfortunately not using the "free surface" boundary condition, but still could be useful somehow in the future. After digging into the src of code_saturne, I found out th...

Re: free surface not moving

Hello, Did anyone manage to download my example and can tell me what's wrong with the model, why I cannot see any motion of the free surface? As already explained before, I presume it could be something to add in the user subroutine related to the boundary condition, but I don't know what. Another w...

Re: free surface not moving

Hello, Thanks Yvan for your quick reply! Yes there is indeed a displacement array, based on vertices, in the Paravis output, but it shows zero displacement magnitude. I tried to use the "warp by vector" filter as well, but still no motion. I guess it is not a matter of visualization (still...

free surface not moving

Hello, I am using code saturne 4.0.6 on Ubuntu 16-04. I simply tried to reproduce the test of the solitary wave (i.e modeling a 2D tank test and imposing a velocity field at the inlet via cs_user_boundary_conditions_ale.f90) to check if the free surface boundary condition from the GUI was working. T...
