ElectricChargeDensity¶
Type: | 0-Tensor, or section |
---|---|
Range: | [v_1, …, v_1] |
Default: | -/- |
Appearance: | optional |
Specifies an electric charge density . The units are coulombs per square meter
Note
A ElectricChargeDensity
is only definable for a physical domain. So, setting BoundaryId
in the parent section is not allowed.
A constant electric charge density can be defined by assigning a scalar:
# define a constant electric charge density
ElectricChargeDensity = ...
For more general cases, a electric charge density may be given as a section in order to deal with space-, time- and parameter-dependent definitions:
# define an electric charge density as a section
ElectricChargeDensity {
Constant {...}
Python {...}
...
}
Field definitions within this section are added. Consult the subsequent sections to see which types of field definitions are allowed.
