Default Help with 2D supersonic impinging nozzle!!!!
Posts: n/a
Hi, I'm modelling a small 2D supersonic nozzle with flow impinging an infinite plate. Re=500000 Mach 3.5

When solving I am recieving a segmentation error after 580 iritations.

Similar models, with impingement distances equal to nozzle exit diameter, have run to 300000+ itr. Current model attempting impingement distances 3 times nozzle exit diameter.

Mesh is extremely fine at exit and impingement zone.

Let me know if you have any ideas or experience to get this thing going.
