Gingred, a general grid generator for 2D edge plasma modeling
Abstract
The current work reports the development of a new general grid generator called Gingred for arbitrary (e.g., number of Xpoints) 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 stepbystep progresses (from "skeleton" grids) of grid generations by nonexperts and new users, the ability to use an arbitrary magnetic configuration, and the more accurate numerical computation by bicubic interpolation of the magnetic flux rather than discrete cosine transform.
