Tokamak free-boundary plasma equilibrium computations in presence of non-linear materials
Résumé
We consider the axisymmetric formulation of the equilibrium problem for a hot plasma in
a tokamak. We adopt a non-overlapping mortar element approach, that couples C0 piece-
wise linear Lagrange finite elements in a region that does not contain the plasma and C1
piece-wise cubic reduced Hsieh–Clough–Tocher finite elements elsewhere, to approximate
the magnetic flux field on a triangular mesh of the poloidal tokamak section. The inclusion of
ferromagnetic parts is simplified by assuming that they fit within the axisymmetric modeling
and a new formulation of the Newton algorithm for the problem solution is stated, both in
the static and quasi-static evolution cases.
