walberla::VelocityGradientRefinement Class Reference

Detailed Description

Adaptive refinement criterion.

A block is refined up to maxLevel if it overlaps the sphere (which must always be well resolved) or if the magnitude of the velocity gradient inside the block exceeds upperLimit. A block is coarsened if its velocity gradient is everywhere below lowerLimit. Otherwise the block keeps its current level.
