Hey Guys I'm currently trying to simulate flow through a de laval nozzle to show under expansion, over expansion and barrel shocks etc. I used GAMBIT for meshing..I am totally new to CFD as I'm currently a undergrad student so forgive my ignorance. I'm able to get the desired results for a mesh with interval size 0.5 with inviscid and laminar flows that too with third order discretization. Results diverge for second order discretization. When I try for a mesh with 0.1 interval the results diverge for all orders of discretization.

Can anyone please help??
