data_array

CenterGrid.data_arraySource

DataArray of center grid coordinates.

The data array has 4 dimensions, which are (ρ, θ, ζ, XYZ). ρ, θ, ζ are radial, poloidal, toroidal coordinates, respectively. They are normalized to edge of the grid, so that the range is (0, 1). XYZ are X, Y, Z coordinates [m].
