MESHJET. A Mesh Generation Package for Finite Element MHD Equilibrium Codes at JET

摘要

MESHJET is a fairly general package and can be used to generate meshes for any finite element code in two space dimensions. These finite element codes are widely used at JET. The first code is for the identification of the plasma boundary and internal flux surfaces from measurements of external fluxes and fields under the assumption that the plasma toroidal density can be represented within a given class of functions. The second code computes plasma equilibrium configurations taking into account a two-dimensional model of the transformer iron core in JET. (Atomindex citation 17:020422)
