.SystemDynamics.Levels.Reverse_Level

Information

Given the following state-space model:

der(x) = f(x,t);

Time reversal can be achieved by placing a minus sign in front of each state equation:

der(x) = -f(x,t);

The Reverse_Level model contains a modulating variable dir that determines the direction of time flow:

der(x) = dir*f(x,t);
