This adds a new property to the
DerivedField
class,is_sph_field
. This isTrue
is the field is an SPH field (i.e. it's ultimately an alias to a particle field where the particle type is an SPH particle type) andFalse
otherwise. This simplifies logic in a few places and for free allows us to fix #2069 and better support particle filters made from an SPH particle type.I've also added a test.
