Gingred, a general grid generator for 2D edge plasma modeling

The current work reports the development of a new general grid generator called Gingred for arbitrary (e.g., number of X-points) 2D magnetic equilibria and plate geometries.

Summary:The current work reports the development of a new general grid generator called Gingred for arbitrary (e.g., number of X-points) 2D magnetic equilibria and plate geometries. A standardization of the construction of a grid is explained, the main command lines are detailed, and examples of snowflake grids are shown. The main advantages of Gingred are the tracking of the step-by-step progresses (from "skeleton" grids) of grid generations by non-experts and new users, the ability to use an arbitrary magnetic configuration, and the more accurate numerical computation by bi-cubic interpolation of the magnetic flux rather than discrete cosine transform.
