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

clean_on_model_update

A list of solver objects to clean when the model is updated

dt_threshold

The threshold used to determine if a previous matrix factor can be reused.

survey

The survey for the simulation Returns ------- SimPEG.electromagnetics.time_domain.survey.Survey
