The Standard Galerkin Method

  • Vidar Thomée
Part of the Springer Series in Computational Mathematics book series (SSCM, volume 25)


In this introductory chapter we shall study the standard Galerkin finite element method for the approximate solution of the model initial-boundary value problem for the heat equation,
$$\eqalign{ & u_t - \Delta u = f{\text{ }}in\:{\text{ }}\Omega ,\:{\text{ }}for\:t > 0, \cr & u = 0\:on\:\partial \Omega ,\:for\:t > 0,\:with\:u(\cdot,0) = v\:in\:\Omega \cr} $$
where is a domain in R d with smooth boundary ∂Ω, and where u = u(x, t), u t denotes ∂u/∂t, and \( \Delta = \sum\nolimits_{j = 1}^d {\partial ^2 /\partial x_j^2 } \) the Laplacian.
