Abstract
We suggest hierarchical a posteriori error estimators for timediscretized Allen–Cahn and Cahn–Hilliard equations with logarithmic potential and investigate their robustness numerically. We observe that the associated effectivity ratios seem to saturate for decreasing mesh size and are almost independent of the temperature.
