Right now, all generated models use the Explicit embedded Runge-Kutta-Fehlberg (4, 5) integrator from GSL. The code generator options JSON could contain a parameter to override this (for instance, a s…

Interesting things about Runge-kutta and Dormand-Prince method
-
I run my code above serval times. But I can get different output sometimes.
I am very confuse that why I can get different output when the input code is same.
It is a bug or I set some wr…

Currently, if there are comments in json, this extension will format it incorrectly. Some properties double-quote will be gone.
It is true that JSON should not have comments on it by specification,…

Use 4th order Runge-Kutta method
I need to figure out equation form. It needs to be written in form: dy/dx = f(x, y). What is 'x', and what is 'y'?

Four selected external libraries have the option to use different algorithms to solve an ODE numerically. I tried to classify them because they use very different names in each library. Some algorithm…

The long form documentation points to the use of RKF78 as the numerical integrator, yet DAISIE v4.1.1 uses lsodes as default. Should this be changed to match DAISIE?

SIM_ball_L3 is not taking all the intermediate integration steps when using an RK4. I believe there is a general problem with integrating over multiple sim objects using a multi-step integrator.

To go through the list:
Explicit embedded Runge-Kutta \(2, 3\) => No term yet
Explicit 4th order \(classical\) Runge-Kutta => Already KISAO\_0000032
Explicit embedded Runge-Kutta-Fehlberg …
