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

Bases: Fields

Base class for storing FDEM fields.

FDEM fields classes are used to store the discrete solution of the fields for a corresponding FDEM simulation; see BaseFDEMSimulation. Only one field type (e.g. 'e', 'j', 'h', or 'b') is stored, but certain field types can be rapidly computed and returned on the fly. The field type that is stored and the field types that can be returned depend on the formulation used by the associated simulation class. Once a field object has been created, the individual fields can be accessed; see the example below.

Parameters:

simulationBaseFDEMSimulation: The FDEM simulation object used to compute the discrete field solution.

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.
