not sure about this particular models
if you wanna make your own erosion mechanism use

Code:

DEFINE_DPM_EROSION (name, p, t, f, normal, alpha, Vmag, mdot)

macro

for more information read ansys fluent customization manual

I don't know the way to do it through UDF
switching between models can be done using fluent GUI
you can use TUI commands to control GUI
and you can use journal file with scheme+TUI to code this switching
