Hello all,

Does anyone know why it is necessary to identify solvers for rhoU, U and rho in fvSolution (instead of just two of these)? One would think that, if we can calculate any two of these, we can obtain the third by multiplication or division, so why the need to specify a solution scheme for all three?

Thanks in advance,

Daniel
