How do you determine the particle diameter after separation from an edge for a Lagrangian wall film?
The particle diameter after separation from an edge equals the maximum of the film height on the face and the value of the rp-variable 'dpm/film-separation-height. The default for 'dpm/film-separation-height is 1E-5.
You can change this, for example, to 1E-4 by:
(rpsetvar 'dpm/film-separation-height 1E-4)
(dpm-parameters-changed)
