I want to use extended boussinesp approximation. There are two variables(tem1 and c1)to solve. The density is a function of tem1 and c1. how to set this kind of buoyancy model in phoenics. Rho=rho-ref*(1-Bt(T-T0)+Bc(C-C0)) I read the polis about buoyancy model, but I doní»t know how to set buoyancy in phoenic. F=(rho-rho-ref)*g or F=rho*g thanks!
