Hello everyone,
Kindly help me to solve 4 simultaneous single order differential equations using RK4 method in EES (Engineering Equation Solver).
How to write code in EES for the particular problem with 4 simultaneous single order differential equations?
Hello,
EES includes a user library (RK4.lib) for solving one single-order ODE (dy/dx=f(x,y)) using the RK4 method. The implemented Runge-Kutta algorithm requires the initial and final values of the independent variable (x), the step size, and the initial value of the dependent variable (y). The function returns only the final value of the dependant variable (y) at x = x_final. It does not provide a parametric table.
If you want to solve 4 simultaneous ordinary differential equations using RK4 in EES, you need to either adjust this library file or just write a new piece of code yourself. If you need more assistance, please write the differential equations here.
Respected Sir, thank you very much. I had sent you the equations by message.
EES includes a user library (RK4.lib) for solving one single-order ODE (dy/dt=2y+cst) using the RK4 method.
Please how I can insert the parametric table of time
Best regards
