The Reduced Dimension Methods of Finite Element Subspaces for Unsteady Partial Differential Equations
摘要
Most partial differential equations (PDEsPartial differential equation (PDEs)) in actual engineering are unsteady time-dependent problems, which also appear in many disciplines and fields. Their finite element (FE) and mixed FE (MFE) methods are among the most effective numerical methods, and their basic theories have been well developed.
