class SimPEG.electromagnetics.frequency_domain.Simulation3DMagneticFluxDensity(mesh, survey=None, forward_only=False, **kwargs)[source]#

Bases: SimPEG.electromagnetics.frequency_domain.simulation.BaseFDEMSimulation

We eliminate \(\mathbf{e}\) using

\[\mathbf{e} = \mathbf{M^e_{\sigma}}^{-1} \left(\mathbf{C}^{\top} \mathbf{M_{\mu^{-1}}^f} \mathbf{b} - \mathbf{s_e}\right)\]

and solve for \(\mathbf{b}\) using:

\[\left(\mathbf{C} \mathbf{M^e_{\sigma}}^{-1} \mathbf{C}^{\top} \mathbf{M_{\mu^{-1}}^f} + i \omega \right)\mathbf{b} = \mathbf{s_m} + \mathbf{M^e_{\sigma}}^{-1}\mathbf{M^e}\mathbf{s_e}\]

Note

The inverse problem will not work with full anisotropy
