HI @ all!
I want to simulate a simple compressiple pipe flow with given pressure and higher tempreture at the inlet using kEpsilon Model with buoyantSimpleFoam. How do I set BC at p_rgh, when pressure inlet goes in z-direction! p = p_rgh + rho*g*z In my case it would be p-rgh = 0.5 - 1.225*-9.81*0.1 --> 0.701 But if i set up the BC of p_rgh with 0.7 it either crashes (when p is 0 but 0.5 at inlet) or it p_rho dosen't converge (when p is 1e-5 but 0.5 at inlet)! |
