Hello --

Is this a nonlinear Poisson-Boltzmann calculation?  If so, and if you don't see any other errors, then the results should be fine.  This message just means that some linear solve steps in the Newton solver for the nonlinear equation had problems converging.

Hi, I apologize if this question has been asked before - I can't seem to find a relevant thread.

I keep getting this error "% MVCS: iters on coarse grid:  100" when I run APBS on my DNA system. Calculations are able to proceed fine, but I'm not sure what this error means, or if I should be concerned if my values are correct or not.

If someone can enlighten me, that'll be great! Thanks!
