nifty7.multi_domain module

class MultiDomain(dct, _callingfrommake=False)[source]

Bases: object

A tuple of domains corresponding to a direct sum.

This class is the domain of the direct sum of fields defined on (possibly different) domains. To make an instance of this class, call MultiDomain.make(inp).

Notes

For consistency and to be independent of the order of insertion, the keys within a multi-domain are sorted. Hence, renaming a domain may result in it being placed at a different index within a multi-domain. This is especially important if a sequence of, e.g., random numbers is distributed sequentially over a multi-domain. In this example, ordering keys differently will change the resulting MultiField.
