一类单边约束问题的数值方法

Numerical Modeling of An Nuilatera Beaming Problem

本文分别基于原始变分形式与对偶混合变分形式,对一类单边约束问题进行了数值求解,提出了求解离散对偶混合变分问题的Uzawa型算法,并用数值例子验证了算法的有效性.

Based on the primal variational formulation and dual mixed variational formulation, two numerical methods are introduced for an unilateral beaming problem, the Uzawa type algorithm resolving discrete dual mixed variational formulation is presented here. The efficiency of algorithm is tested by a numerical example.
