I am doing LES simulation (Smagornisky and WALE) for studying vortex shedding on the wake of cylinders. I am running some test cases, and I found something bizarre. When I plot vorticity magnitude I see some mesh patterns in the graph too. I do not know why it appeared in my plot? is it because of low meshing quality or this might have other reasons like FV schemes? Please see these figures as example : https://ibb.co/QFr5bSs https://ibb.co/P5TNywb Thank you for you help Best
