WebNov 11, 2000 · For each finite volume a "control volume" or finite volume equation is assembled in the form: App*PHI + SUM (Anb*PHInb) = Residual. So, when trying to converge to a steady state solution the residual is the amount by which the a local finite volume is out of balance. i.e., flow of stuff in - flow of stuff out = residual. WebJan 9, 2014 · The mass residual can be missleading sometimes as it is scaled (divided by) the maximum residual of iteration 1 to 5. Fluent plots this scaled residual. If the maximum residual iteration 1 to 5 is already pretty low, the scaled residual will take large values. This would be typical for a interpolated case or a good initial guess.
