class SimPEG.electromagnetics.time_domain.simulation.BaseTDEMSimulation(mesh, survey=None, dt_threshold=1e-08, **kwargs)[source]#

Bases: BaseTimeSimulation, BaseEMSimulation

We start with the first order form of Maxwell’s equations, eliminate and solve the second order form. For the time discretization, we use backward Euler.

Attributes
