The effort source has its causality stroke away from the source.
Potential variables: e: Bondgraphic effort variable f: Bondgraphic flow variable, normalized positive for flows out of the model Parameters: e0: 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:
e = offset + (if time < startTime then 0 else e0)
