hewei Member Join Date: May 2010 Posts: 69 Rep Power: 15	Hello Everyone, I am simulating the laminar steady pipe flow, the flow is driven by pressure gradient. Firstly,I add a constant of dp/dx in the UEqn Matrix, the velocity seems right but the pressure is wrong. Even after changing the varies BCs, the solution still wrong. I find there is pressureGradientExplicitSource codes in the OF, but do somebody could tell me how to add it into the icoFoam solver? Thanks in advance. W.
