Features tested

The following error indicators and element average output are tested.

HFLERI: Heat flux error indicator.
EFLAVG: Element average electric flux.
EFLERI: Electric flux error indicator.
EPGAVG: Element average electric potential gradient.
EPGERI: Electric potential gradient error indicator.

Problem description

All the problems have small coarse meshes with solution gradient risers. Sharp solution gradients are provided by stress concentrations, concentrated heat flux, localized plasticity, etc. Various material types are used to test all the supported element types, and the error indicator appropriate for the material properties is output.

Results and discussion

Error indicators have the highest value where the solution gradients are highest, which is confirmed in the verification tests.
