Cauchy’s Problem for the Modified Biharmonic Equation: Derivation and Decoupled Iterative Methods
摘要
This paper addresses the Cauchy problem for the Modified Biharmonic Equation (MBE). We start by presenting its derivation from the Stokes equations under specific assumptions and boundary conditions. A factorization technique is introduced to manage this fourth-order Cauchy problem, leading to the development of an iterative alternating method for solving the resulting second-order Cauchy problems. The finite element method is used for numerical discretization. The main findings are summarized and analyzed in the context of numerical experiments, with a discussion on their significance. Finally, we outline potential extensions and the limitations of this study.
