class simpeg.electromagnetics.frequency_domain.Fields3DMagneticFluxDensity(simulation)[source]#

Bases: FieldsFDEM

Fields class for storing 3D total magnetic flux density solutions.

This class stores the total magnetic flux density solution computed using a frequency_domain.Simulation3DMagneticFluxDensity simulation object. This class can be used to extract the following quantities:

'b', 'bPrimary', 'bSecondary' and 'h' on mesh faces.
'e', 'ePrimary', 'eSecondary' and 'j' on mesh edges.
'charge' on mesh nodes.
'charge_density' at cell centers.

See the example below to learn how fields can be extracted from a Fields3DMagneticFluxDensity object.

Parameters:

simulationfrequency_domain.Simulation3DMagneticFluxDensity: 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.
