摘要: Nitsche's method [11] is a classical for imposing essential boundary conditions weakly. Unlike the penalty method, it consistent with original differential equation. The strong point of that retains convergence rate underlying finite element whereas standard either requires “very large” parameter, destroying condition number resulting matrix problem, or, in case to be retained, limited first order energy-norm accuracy. In this paper, we give formulation suitable problem fluid-structure interaction. Numerical examples are given.
