ErrorToleranceMarker

Coarsen or refine elements based on an absolute tolerance allowed from the supplied indicator.

Description

The ErrorTolerenceMarker requires an approximation of the error to be supplied via an Indicator. Using the measure of error an element is define for coarsening or refinement using a hard tolerances:

* Refine if the element error is greater than value supplied in "refine" input parameter. * Coarsen if the element error is less than value supplied in "coarsen" input parameter.
