Hello, nI think you will need to make use of DEFINE_IMPINGEMENT and DEFINE_FILM_REGIME UDFs to specify your own user defined film regime. nPlease check the following links.nDEFINE_IMPINGEMENT : : Please check the example which uses the macro Reflect_Particle to reflect the particles which hit the wall.You will need to set up a simple demo model and test the above two UDFs accordingly.nI hope this helps.nRegards,nSDn
