Euler-Cromer ODE Python Routine - Stack Overflow
https://stackoverflow.com/questions/26294940
13.10.2014 · I am using an Euler-Cromer scheme to calculate the position and velocity of Halley's comet. The script tries several values for a time-step (tau) for each value of initial velocity in a range. For each tau value, it runs through the Euler-Cromer routine and compares the total mechanical energy from the beginning of the orbit to the end of the first orbit's cycle.

mechanics. For many problems, a fairly simple approach called the Euler-Cromer Method is sufficient. This method is easy to implement in Python or even lowly MS Excel. Euler Method The simplest numerical method to solve differential equations is the Euler Method. Suppose you want to find xt and you know: . x f x t dt d x dt, dx, 2 2
Semi-implicit Euler method - Wikipedia
https://en.wikipedia.org/wiki/Semi-implicit_Euler_method
In mathematics, the semi-implicit Euler method, also called symplectic Euler, semi-explicit Euler, Euler–Cromer, and Newton–Størmer–Verlet (NSV), is a modification of the Euler method for solving Hamilton's equations, a system of ordinary differential equations that arises in classical mechanics. It is a symplectic integrator and hence it yields better results than the standard Euler method.

Figure Comparison of the Runge-Kutta-Fehlberg adaptive method against the Euler-Cromer scheme for a long time simulation (200 periods) shows a computational example where the Runge-Kutta-Fehlberg method is clearly superior to the Euler-Cromer scheme in long time simulations, but the comparison is not really fair because the Runge-Kutta-Fehlberg method …
