A patch adaptive mesh refinement (AMR) platform is presented. Presently two Navier-Stokes solvers are available within this platform : a MUSCL and DG solver (FLUX AMR) and a multi-species MUSCL solver (MAJIC) for reacting flows. The first solver is based on cell centered approaches of finite volume type, the second solver is based on a cell vertex and a time splitting method. The modifications of AMR treatments, especially those concerning the interpolation at fine-coarse boundaries are detailed. This platform is first tested on the subsonic flow over a deep cavity and secondly on the interaction of a steady planar shock with a H2-air circular diffusion flame.
