Here are the 0/p and 0/U files for each case. They were run on the same size mesh, with the same...

Ata, Wouldn't using a fixedValue at the top and bottom also be a BC that doesn't allow for exiting flow? You could think of it like a moving wall. I can see why zeroGradient wouldn't be accurate,...

Hi ata, I was just trying to make the simulation as close to reality as I could. I made the assumption that far from the body the flow would be unaffected by the cylinder so I gave it the same...

Hi Stefan, I am worried that by using a fixedValue for my outlet then it would unrealistically dampen my karman vortex street as it calculate the flow field as if the flow was uniform at the...

Hi Fernando, The semi-circumference at the inlet was my way of decreasing the number of cells in my overall CV without having a negative effect on accuracy. And no it's not a pipe, if you look at...

Replies: 16 Flow Over a cylinder: Properties not conserved Views: 1,627 Posted By ozzythewise Flow Over a cylinder: Properties not conserved Hello all, I am trying to simulate flow over a cylinder for a validation as I am new to CFD. I am simulating at a Reynolds number of 150. Essentially what happens is everything is going fine, and...
