Hello,

I am new to Telemac 2D and I am encountering a problem with Finite Volumes method.
I want to simulate a fish pass and I already run my case with Finite Elements using K-epsilon effectively. Later I wanted to compare it with the results from Finite Volumes. I tried at first with constant viscosity without problems, but when i changed the model to K-epsilon the water seems to be adding up in the first pool and in the rest of the pools is more or less stable or moving too slow towards the downstream boundary. I am attaching a photo of the results at an early stage (after 3 days of running the water hadn't move significantly)and the simulation files.
I already did a mesh independence study (with the mesh am using) and up to now it gave me correct results. I also tried to change schemes,but so far i get the same result.

Thank you in advance,
Giorgos
