Solution of nonlinear stiff differential equations for a three-phase no-load transformer using a Runge–Kutta implicit method [PDF]
Archives of Electrical Engineering, 2022 The paper presents an approach to differential equation solutions for the stiff problem. The method of using the classic transformer model to study nonlinear steady states and to determine the current pulses appearing when the transformer is turned on is

A Set of New Stable, Explicit, Second Order Schemes for the Non-Stationary Heat Conduction Equation
Mathematics, 2021 This paper introduces a set of new fully explicit numerical algorithms to solve the spatially discretized heat or diffusion equation. After discretizing the space and the time variables according to conventional finite difference methods, these new ...

Schur Decomposition for Stiff Differential Equations
CoRR, 2023 A quantitative definition of numerical stiffness for initial value problems is proposed. Exponential integrators can effectively integrate linearly stiff systems, but they become expensive when the linear coefficient is a matrix, especially when the time step is adapted to maintain a prescribed local error.

Relativistic resistive magneto-hydrodynamics code for high-energy heavy-ion collisions
European Physical Journal C: Particles and Fields, 2023 We construct a relativistic resistive magneto-hydrodynamic (RRMHD) numerical simulation code for high-energy heavy-ion collisions as a first designed code in the Milne coordinates. We split the system of differential equations into two parts, a non-stiff

Explicit Stable Finite Difference Methods for Diffusion-Reaction Type Equations
Mathematics, 2021 By the iteration of the theta-formula and treating the neighbors explicitly such as the unconditionally positive finite difference (UPFD) methods, we construct a new 2-stage explicit algorithm to solve partial differential equations containing a ...
