Hi everyone

I am trying to simulate a tank (Lagrangian) filled with water (Eulerian) subjected to gravity load in order to catch the linear pressure distribution over the wall of the tank, but the contact between water and tank is quite punctual.

I tried to make the mesh finner, define a contact damping property, overlap the external filled eulerian elements with the langrangian mesh (the documentation says that at the begining of the analysis the fluid is pushed out the langrangian elements), but the CPRESS is quit far of the theoretical linear distribution.

Is it possible to model that with CEL analysis? if yes, any suggestion of how to prepare the model and/or define the contact? 

Thanks in advance
