Higher order methods for transient diffusion analysis
TL;DR: In this article, several finite element in time algorithms are developed based on Hermitian expansions of increasing order which are then compared with Pade approximations and alternative Norsett formulas.

Galerkin Methods for Parabolic Equations
Jim Douglas,Todd F. Dupont +1 more
TL;DR: Galerkin-type methods, both continuous and discrete in time, are considered for approximating solutions of linear and nonlinear parabolic problems and bounds reducing the estimation of the error to questions in approximation theory are derived.

Application of the finite element method to heat conduction analysis
TL;DR: In this paper, a variational principle is applied to the transient heat conduction analysis of complex solids of arbitrary shape with temperature and heat flux boundary conditions, and a finite element discretization technique is used to reduce the continuous spatial solution into a finite number of time-dependent unknowns.
