PlaTo

Participant : Hervé Guillard [contact] .

PlaTo (Platform for Tokamak simulation) is a specialized set of softwares dedicated to the geometry of Tokamaks whose main objective is to provide the researchers of the CASTOR team a common development tools. The platform integrates Fortran90 modules using the MPI communication library for parallel computations and some python and C codes. The PlaTo platform has been developed thanks to a 2010 ADT of Inria and the ANR ESPOIR. The construction of this platform integrates the following developments :

• The set-up of a (small) database corresponding to axisymmetric solutions of the equilibrium plasma equations for realistic geometrical and magnetic configurations (JET, ITER and the Tore-Supra upgrade WEST).The construction of meshes is always an important and time consuming task. PlaTo provides meshes and solutions corresponding to equilibrium solutions that will be used as initial data for more complex computations.

• A set of interfaces (PlaTo ToolBox) allowing easy transfer between different solution and mesh formats.

• Numerical templates allowing the use of 3D discretization schemes using finite element/volume methods. At present, several applications (reduced MHD, Euler equations, two fluid Euler model) are available in PlaTo .
