simpeg.maps.TileMap#

class simpeg.maps.TileMap(global_mesh, global_active, local_mesh, tol=1e-08, components=1, **kwargs)[source]#

Mapping for tiled inversion.

Uses volume averaging to map a model defined on a global mesh to the local mesh. Everycell in the local mesh must also be in the global mesh.

Parameters:

global_meshdiscretize.TreeMesh: Global TreeMesh defining the entire domain.
global_activenumpy.ndarray of bool or int: Defines the active cells in the global mesh.
local_meshdiscretize.TreeMesh: Local TreeMesh for the simulation.
tolfloat, optional: Tolerance to avoid zero division
componentsint, optional: Number of components in the model. E.g. a vector model in 3D would have 3 components.

Attributes

`P`	Set the projection matrix with partial volumes
`components`	Number of components in the model.
`global_active`	Defines the active cells in the global mesh.
`global_mesh`	Global TreeMesh defining the entire domain.
`is_linear`	Determine whether or not this mapping is a linear operation.
`local_active`	This is the local_active of the global_active used in the global problem.
`local_mesh`	Local TreeMesh defining the local domain.
`mesh`	The mesh used for the mapping
`nP`	Number of parameters the mapping acts on.
`shape`	Shape of the matrix operation (number of indices x nP)
`tol`	Tolerance to avoid zero division.

Methods

`deriv`(m[, v])
`dot`(map1)	Multiply two mappings to create a `simpeg.maps.ComboMap`.
`inverse`(D)	The transform inverse is not implemented.
`test`([m, num, random_seed])	Derivative test for the mapping.
