walberla::lbm::refinement::CurlBasedLevelDetermination< Filter_T > Class Template Reference

Detailed Description

template<typename Filter_T>
class walberla::lbm::refinement::CurlBasedLevelDetermination< Filter_T >

Level determination for refinement check based on local curl.

If (scaled) vorticity magnitude is below lowerLimit in all cells of a block, that block could be coarsened. If the (scaled) vorticity value is above the upperLimit for at least one cell, that block gets marked for refinement. Else, the block remains on the current level.

The scaling originates from neglecting the actual mesh size on the block to obtain different vorticity values for different mesh sizes.

Parametes upperLimit corresponds to sigma_c, coarsenFactor to c, lowerLimit to c*sigma_c, lengthScaleWeight to r.
