Out of these which will have a greater impact on the final result? 0 Replies Last Post 5 mai 2016, 06:39 UTC+2.Quite generally, near zero results arise from cancellation, and the absolute tolerance that makes sense depends on the sizes of the numbers before cancellation. If a solution component is scaled small, e.g. around 1e-20, and stays in that range, then presumably you can set abstol(i) for that component to 1e-26 to get about 6 digits of accuracy.Note: This discussion is about an older version of the COMSOL Multiphysics® software.
