摘要:
考虑在某种非线性边界条件(即摩擦型滑移或泄漏边界条件)下Stokes方程的有限元逼近。我们提出了一个由变分不等式表述的近似问题,证明了存在唯一性结果,给出了误差估计,并讨论了使用迭代Uzawa型方法的数值实现。提供了几个数值算例来支持我们的理论结果。
英文摘要:
A finite element approximation of the Stokes equations under a certain nonlinear boundary condition, namely, the slip or leak boundary condition of friction type, is considered. We propose an approximate problem formulated by a variational inequality, prove an existence and uniqueness result, present an error estimate, and discuss a numerical realization using an iterative Uzawa-type method. Several numerical examples are provided to support our theoretical results.
