Concatenations#
- class pybamm.Concatenation(*children, name=None, check_domain=True, concat_fun=None)[source]#
A node in the expression tree representing a concatenation of symbols.
- Parameters:
children (iterable of
pybamm.Symbol
) – The symbols to concatenate
Extends:
pybamm.expression_tree.symbol.Symbol
- class pybamm.NumpyConcatenation(*children)[source]#
A node in the expression tree representing a concatenation of equations, when we don’t care about domains. The class
pybamm.DomainConcatenation
, which is careful about domains and uses broadcasting where appropriate, should be used whenever possible instead.Upon evaluation, equations are concatenated using numpy concatenation.
- Parameters:
children (iterable of
pybamm.Symbol
) – The equations to concatenate
Extends:
pybamm.expression_tree.concatenations.Concatenation
- class pybamm.DomainConcatenation(children, full_mesh, copy_this=None)[source]#
A node in the expression tree representing a concatenation of symbols, being careful about domains.
It is assumed that each child has a domain, and the final concatenated vector will respect the sizes and ordering of domains established in mesh keys
- Parameters:
children (iterable of
pybamm.Symbol
) – The symbols to concatenatefull_mesh (
pybamm.BaseMesh
) – The underlying mesh for discretisation, used to obtain the number of mesh points in each domain.copy_this (
pybamm.DomainConcatenation
(optional)) – if provided, this class is initialised by copying everything except the children from copy_this. mesh is not used in this case
Extends:
pybamm.expression_tree.concatenations.Concatenation
- class pybamm.SparseStack(*children)[source]#
A node in the expression tree representing a concatenation of sparse matrices. As with NumpyConcatenation, we don’t care about domains. The class
pybamm.DomainConcatenation
, which is careful about domains and uses broadcasting where appropriate, should be used whenever possible instead.- Parameters:
children (iterable of
Concatenation
) – The equations to concatenate
Extends:
pybamm.expression_tree.concatenations.Concatenation
