Explicit and Implicit Crandall’s Scheme for the Heat Equation with Nonlocal Nonlinear Conditions

Abstract

In this paper, explicit and implicit Crandall’s formulas are applied for finding the solution of the one-dimensional heat equation with nonlinear nonlocal boundary conditions. The integrals in the boundary equations are approximated by the composite Simpson quadrature rule. Here nonlinear terms are approximated by Richtmyer’s linearization method. Finally, some numerical examples are given to show the effectiveness of the proposed method.
