Change wall boundary condition in multiphase?

Jacques

Hi folks,

I want to simulate an inflight-icing problem. My first step is to check the collection efficency (how many droplets impinge on the geometry) of the geometry with the DPM-Model and with a multiphase-model (euler-euler). Now I want to change the boundary condition of the wall, where the droplets impinge, with a UDF so that these droplets can escape the fluid-zone. The boundary condition must only change for the second phase (the phase with the water-droplets). In the DPM-Model this can be done by the "escape-bc".

thanks for your help!
