I have used the Vortex shedding – von Karman instability example:
and have changed the geometry to have an step in the middle. when I run this simulation it works just fine (case_h.sif, step_h.in2d)
Directory: VonKarmanGUI
Solvers: FlowSolve
Tools: ElmerGUI
Dimensions: 2D, Transient
but when I change the geometry in a way to have x and y axises replaced (case_v.sif, step_v.in2d) it diverges! I'm confused!
I would would appreciate if you could help me know what am I doing wrong?
P.S. The reason I want to change the geometry to vertical is because later I want to change th experiment to axisymmetric. so if you can help me do that in one step that would be a great help.
