abstract = {This paper introduces an isoparametric analysis to solve the Vlasov equation with a
semi-Lagrangian scheme. A Vlasov-Poisson problem modeling a heavy ion beam in an
axisymmetric configuration is considered. Numerical experiments are conducted on
computational meshes targeting different geometries. The impact of the computational grid
on the accuracy and the computational cost are shown. The use of analytical mapping or
Bézier patches does not induce a too large computational overhead and is quite accurate.
This approach successfully couples an isoparametric analysis with a semi-Lagrangian
scheme, and we expect to apply it to a gyrokinetic Vlasov solver. },
