Hi, Im simulating high speed fuel injection at apprx 1500 bar with the nozzle 0.090 and I have some serious stability problems.
Since I need good enough resolution at the inlet, atleast 4cells over the nozzle diameter corresponding to 0.00225mm = 22.5 microns its not exactly convergent.
I've tried using stable upwind scheme for the initial timesteps and then changing to central differencing with out success.
My aspect ratio between the cells are okay, about 1.7.
Any ideas, limitedLinear varDriestlimited?
