Detailed Description

The class is an implementation of "direct" remeshing criteria, which maps the error indication, which is usually the value of observed internal variable to the corresponding required element size. The error estimate and global error for error indicator could not be obtained. The error indication value only tells, that the remeshing is necessary, but no information about the actual error are provided. The task of this class is to simply transform the indicator value to corresponding mesh size.
