A mathematical expericent is used to study the dependence of the efficiency of a multimesh relaxation method on the difference approximation of the boundary conditions for the biharmonic equation. Computational results are given, illustrating the rate of convergence of the iterations. A comparison i

In this paper the biharmonic equations are discussed, and the boundary penalty ΓΏnite methods (BP-FEMs) using piecewise cubic Hermite elements are chosen to seek their approximate solutions, satisfying the normal derivative and periodical boundary conditions. Theoretical analysis is made to discover
