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 : https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v211/en/flu_udf/flu_udf_sec_define_impingement.html?q=DEFINE_IMPINGEMENTnDEFINE_FILM_REGIME : https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v211/en/flu_udf/flu_udf_sec_define_film_regime.html. 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
