SMOOTH_LENGTH

provide a function of smoothing length

Options for discrete (locally variable) smoothing length definitions:

SMOOTH_LENGTH($SLflag$) = ( %H_constant%, H ) SMOOTH_LENGTH($SLflag$) = ( %H_spherical%, H_min, L_min, dH/dr, H_max ) SMOOTH_LENGTH($SLflag$) = ( %H_radial%, H_min, L_min, axis_x, axis_y, axis_z, dH/dr, H_max ) SMOOTH_LENGTH($SLflag$) = ( %H_linear%, H_min, L_min, normal_x, normal_y, normal_z, H_max ) SMOOTH_LENGTH($SLflag$) = ( %H_ring%, H_min, L_min, dH/dr, n_x, n_y, n_z, H_max )

See also DSCR. For linking the smoothing length description to the boundary, you need to set the smoothing length tag $SLflag$. An example can be found under SMOOTH_LENGTH.
