流体-固体耦合问题的全离散有限元估计
Fully discrete finite element approximation of a fluid-structure interaction problem
摘要
Abstract
In this paper,the authors consider fully discrete finite element methods for the fluid-structure interaction system. For the time discretization, backward difference algorithm and composite left rectan gular methods are adopted to approximate the continuous derivative and integration with respect to t, re spectively. Existence and uniqueness of finite element solutions are proved,fully discrete error estimates are obtained.
