Hi, everyone.
I was trying to foam a custom case using buoyantBoussinesqSimpleFoam, and I found that the value of internalfield is 0 when I fisrtly opened the file. As I searched , when it comes to incompressible solver, in p file, the P refers to kinematic pressure. So beacuase of that, since it should be 100000/(density of fluid) to express 1atm, for stability of calculation, commonly it's 0. So my question is that is it okay to set interfield value (including other BCs) as 0? it doesn't matter whether it is 100000/(density of fluid) or 0 since p is considered only for gradient form? |
