Well I ended up doing this test albeit with the rotating part behind the cylinder so I could see the vortices going through the rotating region. The differences between the solvers are still pretty...

Okay suppose I have a simulation of flow over a stationary cylinder on a fixed grid with no slip condition (zero wall velocity). Now suppose I start rotating part of the mesh around the cylinder...

Hi Steve, Hrv, Well the cylinder is centered at the origin and of course it is symmetric. I know rotating it with an absolute no slip condition is nonsensical but for the purposes of testing the...

Replies: 12 GGI validation with a cylinder Views: 1,936 Posted By rieuk GGI validation with a cylinder Hi guys, I'm trying to confirm whether GGI is doing what I want it to - I've setup a case with a 2D rotating cylinder with uniform inflow. The boundary condition on the cylinder is fixedValue...
