class simpeg.electromagnetics.time_domain.Fields3DCurrentDensity(simulation)[source]#

Bases: FieldsTDEM

Fields class for storing 3D current density solutions.

This class stores the total current density solution computed using a time_domain.Simulation3DCurrentDensity simulation object. This class can be used to extract the following quantities:

'j' and 'e' on mesh faces.
'dbdt' and 'dhdt' on mesh edges.
'charge' and 'charge_density' at cell centers.

See the example below to learn how fields can be extracted from a Fields3DCurrentDensity object.

Parameters:

simulationtime_domain.Simulation3DCurrentDensity: The TDEM 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.
