I tried the value of under-relaxatioin factors of 0.1, it didn't work. I observed the field, when I turned 1st scheme to 2nd scheme, after several iteration, there was high temperatrue region right...

yes, I have lowered under-relaxation factors from the default value(0.8) to 0.5, it failed still.
the boundary condition:
crossflow: pressure inlet(supersonic) p0=2.4e5 Pa, T0=309K, M=3.5

hello,everyone. I was simulating the flowfield of supersonic crossflow and normal sonic jet. The configuration was a 2d plate,
By using 1st scheme of flow in FLUENT, I can get the convergent...
