TARGET: TArgeting Realistic GEometry in Tokamak code gysela

Participants : Michel Mehrenberger, Nicolas Bouzat, Guillaume Latu, Camilla Bressan, Virginie Grandgirard.

We have worked at CEMRACS2016 on a new variant for the interpolation method to handle both mesh singularity at the origin and non circular geometry. It is based on a non uniform number of points for each closed flux line (intersection of the flux surfaces with the poloidal plane), which are concentric circles in the case of the circular geometry. This strategy, following previous works on curvilinear geometry and hexagonal meshes, should allow to generalize the work in [14] to non circular tokamaks.
