  Hello, I want to use the pressure Far-Field boundary condition instead of the symmetry boundary condition, but when I use pressure Far-Field, the air comes in from around very quickly. what should I do?

  Gauge Pressure is zero? You need to provide the inifnity gauge pressure there corresponding to that Mach Number! Otherwise stick to pressure opening.
