A Source
definition attaches one or several tensor field definitions to a domain or boundary. It is only allowed to set impressed quantities within a Source
section (no material properties). For instance, one may fix the temperature on a certain boundary:
# fix temperature on boundary with identifier 2
Source {
BoundaryId = 2
Temperature = 300
}
Or one may define an electric current density and simultaneously an electric charge density within a domain:
# set a constant electric current flux density
Source {
DomainId = 2
ElectricCurrentDensity = ...
ElectricChargeDensity = ...
}
To capture complex physical situations the definition of the source fields can get complicated. For example, a source field may consist of an analytic expression or of a result Fieldbag
gained from a previous simulation. We refer to the subsequent sections.
Note
Source
terms within one SourceBag section are summed up.
