doughnut_ode, a Fortran90 code which sets up and solves a system of ordinary differential equations (ODE) whose trajectories lie on a torus or doughnut, and for which an exact solution is known.
lorenz_ode, a Fortran90 code which sets up solutions to the Lorenz system of ordinary differential equations (ODE), which exhibit sensitive dependence on the initial conditions.
lorenz96_ode, a Fortran90 code which sets up and solves a system of ordinary differential equations (ODE) devised by Edward Lorenz, as a test of predictability for data assimilation applications.
predator_prey_ode, a Fortran90 code which sets up a pair of predator prey ordinary differential equations (ODE).
stiff_ode, a Fortran90 code which sets up an ordinary differential equation (ODE) which is an example of a stiff ODE.
three_body_ode, a Fortran90 code which sets up a set of ordinary differential equations (ODE) which simulates the behavior of three planets, constrained to lie in a plane, and moving under the influence of gravity, by Walter Gander and Jiri Hrebicek.
two_body_ode, a Fortran90 code which sets up ordinary differential equations (ODE) which simulate the behavior of two bodies, constrained to lie in a plane, moving under the influence of gravity, with one body much more massive than the other.
