Complete grid_subset list

Complete grid_subset list

Following list has been compiled from OMAS schema page and also inclused all custom grid_subsets (not defined in IMAS) defined by this project as negative indices. The column "Present in default" indicates whether the default grid description file initializes the grid_subset. Note: grid subsets with indices 17-21 are intialized but remain empty.

Index	Name	IMAS defined	Present in default	Description
1	nodes	yes	yes	All nodes (0D) belonging to the associated spaces, implicit declaration (no need to replicate the grid elements in the grid_subset structure).
200	nodes_combining_spaces	yes	no	All nodes (0D) belonging to the first space, implicitly extended in other dimensions represented by the other spaces in a structured way.
