6.4.12 Hooking DEFINE_DPM_SPRAY_COLLIDE UDFs

After you have interpreted (Chapter  4) or compiled (Chapter  5) your DEFINE_DPM_SPRAY_COLLIDE UDF, the name of the function you supplied as a DEFINE macro argument will become visible and selectable in the Discrete Phase Model dialog box (Figure  6.4.13) in ANSYS FLUENT.

To hook the UDF, first open the Discrete Phase Model dialog box.
