Field data

Series contain two different type of data – Field and Global data.

• Field data: Large dataset usually tied to a mesh, or a structure of some kind. For these, each step will create a new dataset named after the step number, $e.g$ “0”, “1”, “2”, …
• Global data: Smaller, usually global data. This could be a scalar (total energy, …), a small vector or tensor, … Other than field data, steps of global data share the dataset. I.e. only a single dataset exists for each global.
