On Hierarchical Error Estimators for Time-discretized Phase Field Models
Please always quote using this URN:urn:nbn:de:0296-matheon-6592
- {We suggest hierarchical a posteriori error estimators for time-discretized 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.
