非定常Oseen问题的局部投影稳定化有限元方法
Local Projection Stabilization Finite Element Methods for the Time-dependent Oseen Problems
摘要
Abstract
In this paper, we study the semi-discrete local projection finite element method for non-stationary Oseen problem and prove that this formulation only needs the condition that the projection space and approximation space meet the local weakly inf-sup conditions , and in this case the existence and uniqueness of the solution are proved. The error estimates and stability of the method can be provided by orthogonality interpolation.关键词
