Dear all,
I am trying to solve external flow by using buoyantSimpleFoam. When wall conditions(i.e. B.C. of velocity is zero), I can solve it, but switching to inlet or outlet conditions causes continuity error, which disables me to converge the case. If you know appropriate B.C. for velocity, please teach me. (Particularly, when B.C.s of upper and lower along gravitational direction are set as inlet/outlet condition and B.C. of side is as wall, I could succeed to solve. The B.C. of side is difficult to set as open boundary. If you know some know-how, I would appreciate it if you could help me) Thank you in advance. Sincerely |
