The developement of `Plato` (“*A platform for Tokamak
simulation*”) (http://www-sop.inria.fr/pumas/plato.php ) is
being supported by an ADT action of the D2T. `Plato` is a suite of
data and software dedicated to the geometry and physics of Tokamaks
and its main objective is to provide the Inria large scale initiative
`FUSION` teams working with plasma fluid models with a common
development tool. The construction of this platform will integrate the
following developments.

A (small) database corresponding to axi-symmetrical solutions of the equilibrium plasma equations for realistic geometrical and magnetic configurations (ToreSupra, JET and ITER). The construction of meshes is always an important time consuming task.

`Plato`will provide meshes and solutions corresponding to equilibrium solutions that will be used as initial data for more complex computations.A set of tools for the handling, manipulation and transformation of meshes and solutions using different discretisations (P1, Q1, P3, etc)

Numerical templates allowing the use of 3D discretization schemes using finite element schemes in the poloidal plane and spectral Fourier or structured finite volume representations in the toroidal one.

Several applications (Ideal MHD and drift approximation) used in the framework of the Inria large scale initiative

`FUSION`.
