The type of disjoint flux distribution.
EnumeratorDISTRIBUTION\_TYPE\_UNSPECIFIED Unspecified disjoint flux distribution type.
DISTRIBUTION\_TYPE\_PROPORTIONAL Flux distributed proportionally to the area of each disjoint surface.
NoteWith this distribution type, the power emitted by one disjoint surface is equal to the power defined in the surface source properties multiplied by the ratio of area of the disjoint surface to the total area. DISTRIBUTION\_TYPE\_EVEN Flux distributed evenly among the disjoint surfaces.
NoteWith this distribution type, each disjoint surface emits the same power. The power of each disjoint surface is equal to the power defined in the surface source properties divided by the number of surfaces.
