 February 8, 2007, 06:43 Residuals in the whole field #1 Jeremie Vareilles Guest   Posts: n/a I have some troubles with continuity (residuals never decrease under 10-3) on a k-epsilon RNG for natural convection in vertical channel. That not my only convergence criterium. I check velocity, mass flow rate, etc, in the channel too. But I think that's not enough. My domain is not simple (channel and whole experiment room are simulated). My problem of continuity may occur outside the channel (resultas are good inside the channel). But the residual given by FLUENT is computed as a mean value of the whole domain. Does someone know how to display (or compute) residual for each cells of the domain?

Than it's possible to display residuals. An other problem : Continuity is not given. Or, most of problems occur on continuity. Mass imbalance is given. But the continuity can be bad, even if Mass imbalance is good. So does someone know how what does Continuity mean (compared to mass imbalance)?How should the continuity value be interpreted?
