6.2.25 Hooking DEFINE_TURB_SCHMIDT UDFs

After you have interpreted (Chapter  4) or compiled (Chapter  5) your DEFINE_TURB_SCHMIDT UDF, the name of the function you supplied as a DEFINE macro argument will become visible and selectable in the Viscous Model dialog box in ANSYS FLUENT. To hook the UDF, first open the Viscous Model dialog box (Figure  6.2.34) and set up a turbulence model.

If you select k-epsilon from the Model list, you must not select RNG from the k-epsilon Model list.

Next, select the function name (e.g., udf_sct::libudf) from the Turbulent Schmidt Number drop-down list under User-Defined Functions in the Viscous Model dialog box, and click OK.

The Species Transport model must be selected in the Species Model dialog box for the Turbulent Schmidt Number drop-down list to be visible in the Viscous Model dialog box.
