venkatesh Guest Posts: n/a	Hi , I want to simulate the external compressible flow over a object approximatley similar to cone with mach number 2. What is the bounary condition i should use for free boundary ? If as specified by the manual to use the Pressure Far-Field Boumdary Condition the domain 10-20 times of the charecteristic dimension is mandatory ?? I dont have resourses for such a big domain... what is the alternate Boundary Condition I can use Thanks Venkatesh.V
