SimPEG.maps.ChiMap#
- class SimPEG.maps.ChiMap(mesh=None, nP=None, **kwargs)[source]#
Bases:
SimPEG.maps.IdentityMapMapping that computes the magnetic permeability given a set of magnetic susceptibilities.
Where \(\boldsymbol{\chi}\) is the input model parameters defining a set of magnetic susceptibilities,
ChiMapcreates a mapping \(\boldsymbol{\mu}(\boldsymbol{\chi})\) that computes the corresponding magnetic permeabilities of every element in \(\boldsymbol{\chi}\); i.e.:\[\boldsymbol{\mu}(\boldsymbol{\chi}) = \mu_0 \big (1 + \boldsymbol{\chi} \big )\]where \(\mu_0\) is the permeability of free space.
- Parameters
- mesh
discretize.BaseMesh The number of parameters accepted by the mapping is set to equal the number of mesh cells.
- nP
int Set the number of parameters accepted by the mapping directly. Used if the number of parameters is known. Used generally when the number of parameters is not equal to the number of cells in a mesh.
- mesh
Methods
deriv(m[, v])Derivative of mapping with respect to the input parameters.
inverse(m)Apply the inverse mapping to an array.
