simpeg.electromagnetics.frequency_domain.Fields3DElectricField

class simpeg.electromagnetics.frequency_domain.Fields3DElectricField(simulation)

Bases: FieldsFDEM

Fields class for storing 3D total electric field solutions.

This class stores the total electric field solution computed using a frequency_domain.Simulation3DElectricField simulation object. This class can be used to extract the following quantities:

• 'e', 'ePrimary', 'eSecondary' and 'j' on mesh edges.

• 'h', 'b', 'bPrimary' and 'bSecondary' on mesh faces.

• 'charge' on mesh nodes.

• 'charge_density' at cell centers.

See the example below to learn how fields can be extracted from a Fields3DElectricField object.

Parameters:

simulationfrequency_domain.Simulation3DElectricField

The FDEM simulation object associated with the fields.

Attributes

aliasFields	The aliased fields of the object.
approxSize	Approximate cost of storing all of the known fields in MB.
dtype	Python data type(s) used to store the fields.
knownFields	The field solutions and where they are discretized on the mesh.
mesh	Mesh used by the simulation.
simulation	The simulation object used to compute the field solution.
survey	Survey used by the simulation.

Methods

startup()

Run startup to connect the simulation's discrete attributes to the fields object.
