In the results of the simulation of the Basics of Fluid Dynamics learning track, the residual values for continuity tend to be higher. Why are the continuity residual values higher compared to other properties?

Hello, Nindi,

According to Fluent's User Guide, the continuity residual is initial-guess-dependent and startup-dependent. The continuity residuals we see in it are scaled by its behavior on the first 5 iterations. Then, a better initial guess may lead to a higher continuity residual.
