β¦ Synopsis
Fully discrete mixed finite element method is considered to approximate the solution of a nonlinear second-order parabolic problem. A massively parallel iterative procedure based on domain decomposition technique is presented to solve resulting nonlinear algebraic equations. Robin type boundary conditions are used to transmit information between subdomains. The convergence of the iteration for each time step is demonstrated. Optimal-order error estimates are also derived. Numerical examples are given. (~) 2000 Elsevier Science Ltd. All rights reserved.

This work deals with the efficient numerical solution of nonlinear parabolic problems posed on a two-dimensional domain β¦. We consider a suitable decomposition of domain β¦ and we construct a subordinate smooth partition of unity that we use to rewrite the original equation. Then, the combination of
A mixed formulation of the finite element method is used to establish a higher-order incremental method for the solution of parabolic equations. The displacement and velocity fields (in the terminology of Solid Mechanics) are approximated independently in time using a hierarchical, adaptive basis. T
