Numerical Solution of ODEs

2013
We look at the method of lines using standard initial-value problem (IVP) software for stiff problems. Both spectral methods and compact finite differences are used for the spatial derivatives. We look briefly at the transverse method of lines, which instead uses standard boundary value problem (BVP) software that has automatic mesh selection.

Analytical and numerical solutions of time and space fractional advection-diffusion-reaction equation

Communications in nonlinear science & numerical simulation, 2019
In this paper, analytical and numerical solutions of time and space fractional advection-diffusion-reaction equations are found. In general, by using Lie transformations, it is possible to reduce the fractional partial differential equations into ...

Numerical Solution of Equations

2020
Solving equations, and systems of equations, of all kinds, both algebraic and transcendental, is a very frequent task in a physicist’s life. Very often equations, particularly algebraic nonlinear equations and transcendental equations, have no analytical solutions. In this case we look for approximate numerical solutions.

Numerical Solution of an Interdiffusion Problem

SIAM Journal on Numerical Analysis, 1992
The interdiffusion problem of two alloys is studied. It is assumed that the alloys are brought into contact and then heated to a fixed temperature. The problem is considered to be one-dimensional, the time dependent change of concentration being caused by convective and diffusive fluxes, with the diffusion coefficient depending on the local ...

Reproducibility and the Concept of Numerical Solution

Minds and Machines, 2019
In this paper, we show that reproducibility is a severe problem that concerns simulation models. The reproducibility problem challenges the concept of numerical solution and hence the conception of what a simulation actually does. We provide an expanded picture of simulation that makes visible those steps of simulation modeling that are numerically ...
