modelstepSf
Step flow source of the Modelica bond graph library
Extends from Interfaces.ActiveOnePort (Partial model invoking one bondgraphic connector).
Information
The step flow source is an active OnePort element. It inherits the effort and flow variables from the active OnePort. The step flow to be generated is modeled as a set of three parameters.The flow source has its causality stroke at the source.
Potential variables: e: Bondgraphic effort variable f: Bondgraphic flow variable, normalized positive for flows out of the model Parameters: f0: Height of step to be generated (default value = 1) offset: Offset of step to be generated (default value = 0) startTime: Start time of step to be generated (default value = 0)
Equations:
f = offset + (if time < startTime then 0 else f0)
