 The classical SU(_N_) spin dynamics in Sunny generalizes the Landau-Lifshitz equation for $S > 1/2$ quantum spins. Linearizing and quantizing SU(_N_) dynamics yields a generalization of spin wave theory involving multi-flavor bosons.
 
 Codes like [Spirit](https://github.com/spirit-code/spirit) and [Vampire](https://vampire.york.ac.uk/) focus less on capturing quantum effects, but may be good options for classical dynamics of pure dipoles.
