  We describe and benchmark a method to accurately calculate the quantum
droplet states that can be produced from a dipolar Bose-Einstein condensate.
Our approach also allows us to consider vortex states, where the atoms
circulate around the long-axis of the filament shaped droplet. We apply our
approach to determine a phase diagram showing where self-bound droplets are
stable against evaporation, and to quantify the energetics related to the
fission of a vortex droplet into two non-vortex droplets.
