Semi-Lagrangian simulations on polar grids: from diocotron instability to ITG turbulence

Résumé

While developing a new semi-Lagrangian solver, the gap between a linear Landau run in 1D 1D and a 5D gyrokinetic simulation in toroidal geometry is quite huge. Intermediate test cases are welcome for checking the code.We consider here as building block, a 2D guiding center type equation on an annulus.We rst revisit a 2D test case previously done with a PIC approach [15] and detail the boundary conditions. We then consider a 4D drift kinetic slab simulation for which we give some rst results of a new conservative method.
