DnWingCriterion Class Reference

Detailed Description

Refinement criterion adapted for wing surfaces.

This is a specialized mesh refinement criterion for tapered wing surfaces. To provide a reasonable mesh quality, the maximum edge length parameter is scaled according to the local chord. Hence, the maxlen parameter should be given in terms of the maximum chord.
