- class DomainTuple(domain, _callingfrommake=False)#
Ordered sequence of Domain objects.
This class holds a tuple of
Domainobjects, which together form the space on which a
Fieldis defined. This corresponds to a tensor product of the corresponding vector fields.
DomainTuples should never be created using the constructor, but rather via the factory function
- property axes#
axis indices of the underlying domains
tuple of tuple of int
- static make(domain)#
Returns a DomainTuple matching domain.
This function checks whether a matching DomainTuple already exists. If yes, this object is returned, otherwise a new DomainTuple object is created and returned.
- static scalar_domain()#
Returns the uniform volume element for a sub-domain of self.
spaces (int, tuple of int or None) – Indices of the sub-domains to be considered. If None, the entire domain is used.
If the requested sub-domain has a uniform volume element, it is returned. Otherwise, None is returned.
- Return type:
float or None
- property shape#
number of pixels along each axis
The shape of the array-like object required to store information defined on the DomainTuple.
tuple of int
- property size#
total number of pixels.
Equivalent to the products over all entries in the object’s shape.
Returns the total volume of self or of a subspace of it.
spaces (int, tuple of int or None) – Indices of the sub-domains of the domain to be considered. If None, the total volume of the whole domain is returned.
the total volume of the requested (sub-)domain.
- Return type:
