  Finite element discretisation of the Dirichlet biharmonic problem by Bogner-Fox-Schmit(bicubic Hermite)elements leads to a symmetric positive definite coefficient matrix.

Multiphysical problems are often described by coupled problems with largely differing timescales.Frequently,a low dimensional subsystem is active,while the majority of unknowns is latent.
