I am trying to solve this equation using Runge Kutta 4th order: applying d2Q/dt2=F(y,x,v) and dQ/dt=u Q=y in my program. I try to run the code but ...

I am trying to use a Runge Kutta method to simulate the motion of the Earth around the Sun in C, I cannot see why but my code does not update the valu ...

I am tring to solve the equation of motion of charged particle in planetary magnetic field to see the path of the particle using Forward Euler's and R ...

I am trying to simulate a planet going around the sun with the RK4 algorithm. This is my code that i tried: When running this code i receive an "o ...

I'm creating a program to compare two graphs, using the Runge Kutta method to solve an ODE. Ideally the resulting plots would be directly on top of ea ...

I want to make RK4 with the numba for speed-up. I'm a beginner using the numba. Why can't the numba understand my code? The simple code is following ...

I'm learning C by myself using real-world examples. Given my background (physics) I'm implementing a 4th order Runge-Kutta method. I have a function w ...

I really need your help. I don't understand why my program works incorrectly. I need to solve this using Runge Kutta Method Analytical answer: y(x) ...

so I have 2 second order nonlinear ODE and after applying the state-space theorm I have 4 first order ODE. I'm trying to apply RK4 but I think I'm doi ...

I am working on combining a Generalized Weighted Residual Method with an RK4. The GWRM part decomposed the PDEs to the spectral space where the unknow ...

I tried everything and looked everywhere but can't find any solution for my question. this is the code where I'm trying to replace the ode45 with t ...

I need to integrate a system of ODES using an adaptive RK4 method with stepsize control via step doubling techniques. The problem is that the program ...

I'm trying solve a system of coupled ordinary differential equations, formed by 7 ODEs in python, using solve_ivp or either implement a fuction for RK ...

I'm trying to solve the 3 body problem with solve_ivp and its runge kutta sim, but instead of a nice orbital path it outputs a spiked ball of death. I ...

I am currently working on implementing the numerical method RKF45 (Runge-Kutta-Fehlberg-45) with adaptive step size into python 3 and I believe I am r ...

So im tasked with using the 4th order Runge Kutta Meathod to solve the 2nd order differential equation of a damped occilator. my function for the run ...

I am making a simulation where you create different balls of certain mass, connected by springs which you can define (in the program below all springs ...

I am trying to model a system of coupled ODEs which represent a three-box ocean model of phosphorous concentration (y) in the low-latitude surface oce ...

I am trying to solve a Differential Equation with 4th Order Runge - Kutta method in Python3. The function is deliberately made so that the solution go ...

I am trying to solve an ODE with two variables. I do not understand why or how I have created a tuple here. The function f should be f = 10 - x - (4xy ...
