%H_spherical%

spherical smoothing length distribution around points or geometry elements

Form a ball of radius L_min and construct the smoothing length around it.

SMOOTH_LENGTH($SLflag$) = ( %H_spherical%, H_min, L_min, dH/dr, H_max )

H_min: minimum smoothing length L_min: radius of "ball" within which the smoothing length is kept on the level of H_min dH/dr: increase rate of H outside of the L_min-ball with respect to the (Euclidean) distance (based on unit lengths) H_max: maximum smoothing length
