Simgua 3.3

Simgua is a powerful modeling tool similar to VenSim or STELLA that can solve complex simulation problems with surprising ease. Simgua's foundation is an intuitive flow and stock principle. Stocks or reservoirs of some material are connected by a series of flows. The stocks can contain any material--water, air, dollars, or even chickens--and the quantity of the flows are specified by the user using mathematical equations or formulas.
