Geometry (r, theta)

The geometryRTheta folder contains all the code describing methods which are specific to a 2D curvilinear geometry containing a singular point. It is broken up into the following sub-folders:

• Advection operator - Code describing advection operator and time integration methods used on 2D polar domain.
• Advection Field finder - Code describing computation of the advection field given to the advection operator.
• Geometry RTheta - All the dimension tags used for a gyrokinetic semi-Lagrangian simulation in a curvilinear geometry.
• Initialization - Initializes the simulations on a 2D polar domain.
• Spline interpolator in polar coordinates - Code describing interpolation methods on 2D polar domain.
• Polar Poisson solver - Code describing the polar Quasi-Neutrality solver.
• Predictor-corrector methods - The methods to solve in time the equations system.
