Information

This is the general System Dynamics unrestricted additive Rate element, whereby the rate itself is determined by two variables in its laundry list. The indicated direction of mass flow simply denotes the direction of positive mass flow. However if the control signal of the rate assumes a negative value, mass will flow in the opposite direction.
