Implement der2011

[jorgepiloto]

💻 Solver request: der2011

The original algorithm devised by Der makes use of a universal free-parameter, with rational formulae for the initial guess, and the Laguerre method as the root solver. The velocity vectors construction exploits a radial + chord-wise construction.

The majority of the current test-suite cases comes from this paper, although for some reason I never ended up implementing this solver...

The original paper can be downloaded from here. The steps to solve for the problem are listed down.
