Switch to filling
Overview and Key Concepts
The Switch to filling activity closes the output side of the specified object(s) and 
		opens the input side. It can be considered as a shortcut for a call to openinput(),
		closeoutput() followed by a recalculation request of the flow rates.

Connectors
The Switch to filling activity only allows one connector out. See Adding and Connecting Activities for more information.

Object(s)/ Group / Array

		enters the activity, the expression will be parsed recursively such that arrays of groups or groups will 
		be properly handled.
