This is the source code of an eXtended Finite Element Method application for acoustic based on an in-house open-source X-FEM library. .
- Disspative porous materials are considered by Equivalent fluid model and Biot coupling equations [1]
- Enforcememnt of interface conditions by a proposed generalized Nitsche's method [2]
- Transfer matrix method is coupled with X-FEM to model thin porous layers [3]
Most of work is done in Ecole Centrale Nantes for a Phd project supervised by Prof. G.LEGRAIN and Prof.O.Dazel
