6.4.2 Hooking DEFINE_DPM_BODY_FORCE UDFs

After you have interpreted (Chapter  4) or compiled (Chapter  5) your DEFINE_DPM_BODY_FORCE 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  6.4.2) in ANSYS FLUENT.

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