Explicit Euler solvers have a low variability in the amount of time required to evaluate a time step compared with implicit and variable step solvers. Also when an explicit Euler solver is inlined (see Dymola User Manual 1B Section 2.7.6) and the appropriate Dymola flags set, this typically results in a fast/efficient solver.

Let’s consider the following equation. The solution of this differential equation is the following. What we are trying to do here, is to use the Euler method to solve the equation and plot it alongside with the exact result, to be able to judge the accuracy of the numerical method. Phương pháp Euler là một phương pháp bậc một, có nghĩa là sai số cục bộ (sai số mỗi bước) tỷ lệ thuận với bình phương của kích thước bước, và sai số tổng thể (sai số tại một thời điểm nào đó) tỷ lệ thuận với kích thước bước.

but this is wrong and you can check it by comparing your "explicit" and "implicit" results: they should slightly diverge but with this formula they will diverge drastically. To understand the implicit Euler method, you should first get the idea behind the explicit one. Explicit Euler Method to Solve System of ODEs in MATLAB In this tutorial, I am going to show a simple way to solve system of first order ordinary differential equations (ODE) by using explicit Euler method . The Explicit Euler formula is the simplest and most intuitive method for solving initial value problems. At any state \((t_j, S(t_j))\) it uses \(F\) at that state to “point” toward the next state and then moves in that direction a distance of \(h\).

Euler’s method is the simplest approach to computing a numerical solution of an initial value problem. However, it has about the lowest possible accuracy. If we wish to compute very accurate solutions, or solutions that are accurate over a long Funnily enough, the less robust method (Forward Euler) is refusing to work as highlighted in the post. The reason I am doing an Explicit Euler is to compare it with other numerical methods! Moreover, the question is meant to ask in terms of code as I feel I am always under Mathematica's will when I use NDSolve, and I want to know how to navigate its built-in AI. Since we know that interpolants and finite differences become more accurate as \(h\to 0\), we should expect that from Euler’s method too.
