I am currently working on modeling flow through a butterfly valve when it is open/closed and at a few other angles. I have gotten the closed version to work and now I am trying to get the open version to work using the same model (Laminar flow, 1-inlet/1-outlet, same flow velocity, same solving methods). However, after multiple attempts I keep getting results that are inf (look at picture below titled 'contour prob'). My continuity is going off the charts so I assumed to change my mesh and make it a higher density, but to no avail. I have tried multiple meshing attempts all different so I am not sure if this is the problem anymore.
Could anyone provide insight onto what may be causing this? Like I said the closed version worked and now all I did was turn the valve to be open in SpaceClaim.
Below I will post a pic of the mesh as well, keep in mind this is just one of MANY meshes I have tried.
