A Nitsche-type Method for Helmholtz Equation with an Embedded Acoustically Permeable Interface
Esubalewe Lakie Yedeg, Eddie Wadbro, Peter Hansbo +2
We propose a new finite element method for Helmholtz equation in the situation where an acoustically permeable interface is embedded in the computational domain. A variant of Nitsc…
