Abstract:
Weak Dirichlet-type boundary conditions are especially important in embedded domain methods such as the Finite Cell Method. Well suited are Nitsche-type methods which have been extended to problems of linear elasticity or fluid dynamics. In principle, they consist of two parts. The first part is negative and stems from an suitable Lagrange multiplier. The second part is positive and stems from the minimization of the difference between the primal solution at the boundary minus the imposed values...     »
