This will be available in the next release. Ordinarily I’d quickly backport it to 1.4 for you but the new indicator is tied to more comprehensive changes of the library and unfortunately not easy to extract.

In general, smooth indicators are used by the resolved particle code to model particles with a porous boundary layer (in HLBM). See e.g.
