PLANES relies on a set of Matlab scripts and is completly open-source.
This tool provides several methods of discretisation for fields and several types of resolution strategies which are listed below.
Methods of discretisation¶
- 3 Nodes Triangles (TR3)
- 6 Nodes Triangles (TR6)
- Triangle with Hermite interpolation (H12)
- Finite Element Method (FEM)
- Discontinuous Galerkin Method (DGM)
- Plane Waves for multilayer systems
As the main goal of this softare is to provide an easy-to-configure, reliable way to model and resolve complex systems involving porous materials it’s possible to identifying all those different materials/aproximation :
- equivalent elastic solid
- equivalent fluid
- limp model
- Biot model (1998 formulation)
- Biot model (2001 formulation)
It is, of course, possible to specify periodicity conditions (for code-simplicity sake, periodicity must be defined on compatible boundaries).
Through its quite simple code base and its script-based architecture, PLANES is really flexible and is sometimes used to experiment new techniques. The experimentation on FEM & DGM coupling leaded to the introduction of method coupling abilities.
It’s therefore possible to couple FEM & DGM methods, using compatible or incompatible meshes.
