Finite difference magnetoelastic simulator. [PDF]
Open Res Eur, 2021 We describe an extension of the micromagnetic finite difference simulation software MuMax3 to solve elasto-magneto-dynamical problems. The new module allows for numerical simulations of magnetization and displacement dynamics in magnetostrictive materials and structures, including both direct and inverse magnetostriction.

Finite-Difference Operators for 2D problems [PDF]
Bulletin of the Polish Academy of Sciences: Technical Sciences, 2020 This paper presents the concept of using algorithms for reducing the dimensions of finite-difference equations of two-dimensional (2D) problems, for second-order partial differential equations.

Finite Difference of Adjoint or Adjoint of Finite Difference? [PDF]
Monthly Weather Review, 1997 Abstract Adjoint models are used for atmospheric and oceanic sensitivity studies in order to efficiently evaluate the sensitivity of a cost function (e.g., the temperature or pressure at some target time tf, averaged over some region of interest) with respect to the three-dimensional model initial conditions. The time-dependent sensitivity, that is the

A two-dimensional linear elasticity problem for anisotropic materials, solved with a parallelization code [PDF]
INCAS Bulletin, 2010 The present paper introduces a numerical approach of static linear elasticity equations for anisotropic materials. The domain and boundary conditions are simple, to enhance an easy implementation of the finite difference scheme. SOR and gradient are used

Hybrid finite difference/finite element immersed boundary method [PDF]
International Journal for Numerical Methods in Biomedical Engineering, 2016 The immersed boundary method is an approach to fluid‐structure interaction that uses a Lagrangian description of the structural deformations, stresses, and forces along with an Eulerian description of the momentum, viscosity, and incompressibility of the
