ElectromagneticSourceAssignment Properties
An ElectromagneticSourceAssignment
object describes the source
of an electromagnetic model. An ElectromagneticModel
object contains a vector of ElectromagneticSourceAssignment
objects in its Sources.SourceAssignments
property.
Create electromagnetic source assignments for your model using the electromagneticSource
function.
Properties
RegionType
— Geometric region type
"Face"
for a 2-D model | "Cell"
for a 3-D model
Geometric region type, specified as "Face"
for a 2-D model or
"Cell"
for a 3-D model.
Data Types: char
| string
RegionID
— Region ID
vector of positive integers
Region ID, specified as a vector of positive integers. Find the face or cell IDs by
using pdegplot
with the
FaceLabels
or CellLabels
name-value argument set
to "on"
.
Data Types: double
ChargeDensity
— Charge density
real number | function handle
Charge density, specified as a real number or a function handle. Use a function handle to specify a charge density that depends on the coordinates.
Data Types: double
| function_handle
CurrentDensity
— Current density
real number | column vector | function handle | ConductionResults
object
Current density, specified as a real number, a column vector, a function handle, or
a ConductionResults
object. Use a function handle to specify a
current density that depends on the coordinates.
For magnetostatic analysis, the current density must be a real number for a 2-D
model, a column vector of three elements for a 3-D model, a function handle for a 2-D or
3-D model, or a ConductionResults
object for a 3-D model.
For harmonic analysis with the electric field type, the current density must be a
column vector of two elements for a 2-D model, a column vector of three elements for a
3-D model, or a function handle for a 2-D or 3-D model. The toolbox multiplies the
specified current density value by -i
and by frequency.
For harmonic analysis with the magnetic field type, the current density must be a scalar for a 2-D model, a column vector of three elements for a 3-D model, or a function handle for a 2-D or 3-D model. The toolbox uses the curl of the specified current density.
Data Types: double
| function_handle
Magnetization
— Magnetization
column vector | function handle
Magnetization, specified as a column vector of two elements for a 2-D model, a column vector of three elements for a 3-D model, or a function handle. Use a function handle to specify a magnetization that depends on the coordinates.
Data Types: double
| function_handle
