Hi SD,nDEFINE_FILM_REGIME with FILM_USER_0 and new rebound code (from DEFINE_DPM_BC) is working, but is not simulating the rebound. The droplet trajectory stops right after hitting the wall. The droplet mass is not absorbed into the Film mass. nThough the DPM-Film particle update shows both absorbed and rebound at the same time for the same droplet, nothing is updated within the impingement-Film model results.nThe Transcript on the console shows - Eulerian wall film particles: absorbed = 1, splashed = 0, rebound = 1nnPlease let me know if there is a workaround.nnThanks,nJo
