SimPEG.meta.SumMetaSimulation

class SimPEG.meta.SumMetaSimulation(simulations, mappings)

Bases: MetaSimulation

An extension of the MetaSimulation that sums the data outputs.

This class requires the mappings have the same input length and each simulation to have the same number of data.

This could be useful for a linear problem where each simulation tackles a different subset of the model.

Parameters:

simulations(n_sim) list of SimPEG.simulation.BaseSimulation

mappings(n_sim) list of SimPEG.maps.IdentityMap

Attributes

clean_on_model_update	A list of solver objects to clean when the model is updated
counter	SimPEG Counter object to store iterations and run-times.
deleteTheseOnModelUpdate	A list of properties stored on this object to delete when the model is updated
mappings	The mappings paired to each simulation.
mesh	Mesh for the simulation.
model	The inversion model.
needs_model	True if a model is necessary
sensitivity_path	Path to directory where sensitivity file is stored.
simulations	The list of simulations.
solver	Numerical solver used in the forward simulation.
solver_opts	Solver-specific parameters.
survey	The survey for the simulation.
verbose	Verbose progress printout.
