unfortunately, we don’t plot the continuity residuals. You can check the values in the course of the simulation, look for something like this in the log:
time step continuity errors : sum local = 4.98893e-05, global = 1.58819e-20, cumulative = 7.4834e-21
On the positive side, we are working on a more elaborate way to monitor convergence. Then, you will have more control over quantities to watch.
