This is a modern Fortran (2003/2008) implementation of Hairerʼs DOP853 ODE solver. The original Fortran 77 code has been extensively refactored, and is now object-oriented and thread-safe, with an easy-to-use class interface. DOP853 is an explicit Runge–Kutta method of order 8(5,3) due to Dormand & Prince (with stepsize control and dense output).
