      Hi !


      I study the behavior of a half-filled cylinder with water faced to a seism.Thus I use a transient profile (sampleprofile transient 4096 0) and a cylinder which could be used in petrochemistry for instance with big dimensions (diameter 20m, height 12.5m).


      I want to drop the residues of  my calcul.
      For that purpose, I try to have a Courant number C<0.3. For that I supposed the maximal velocity of the fluid in my simulation is (2*g*h)^(0.5), with h=12.5m. Indeed the absolute acceleration of my seisme is far less than gravity acceleration.
      However I have residues of thecontinuity equation which reach 0.1.

      Do you have any tips to help me ?


      Thanks

      Hi !


      Thanks for your interest, I respectively send you my geometry(radius=10m, diameter=20m), my meshing (element size=0.7m on the envelop), my setup General, my transient profile, my model VOF ( the model is also viscous-laminar), the data of my solution as well as my volume fraction after mark and patch.
      I can give you others information if you need.

      Regards.
