/**
|
|
* Driver of 3Di file format.
|
|
*
|
|
* The result 3Di NetCDF file is based on CF-conventions with some additions.
|
|
* It is unstructured grid with data stored in NetCDF/HDF5 file format.
|
|
* A division is made between a 1D and 2D which can be distinguished through
|
|
* the prefixes “MESH2D” and “MESH1D”. For both meshes the information is present
|
|
* in coordinate, id, and type variables.
|
|
*
|
|
* A version of the data scheme is not present yet.
|
|
*
|
|
* The 2D Mesh consists of calculation Nodes that represents centers of Faces.
|
|
* There is no concept of Vertices in the file. The vertices that forms a face
|
|
* are specified by X,Y coordinates in the "Face Contours" arrays. The "lines"
|
|
* represent the face's edges and are again specified by X,Y coordinate of the
|
|
* line center. Data is specified on calculation nodes (i.e. dataset defined on faces)
|
|
* and on lines (i.e. dataset defined on edges - not implemented yet)
|
|
*
|
|
* The 1D Mesh is present too, but not parsed yet.
