DESCRIPTION
Simgua is a powerful modeling tool similar to VenSim, PowerSim 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. This seemingly simple base can be used to model incredibly complex systems including the following:

Environmental Models:

  • Water and Wastewater Treatment
  • Air Treatment
  • Pollutant Transport
  • Ecological Models
Other Models:
  • Models of Industrial Processes
  • Economical Models
  • Demographic Models

    ZOZETTE  Simulation tool for so called system dynamics problems.

    Simgua is not so easy to use. You cannot interact graphically with flow, stock and links icons... Compare with STELLA or MADONNA.

    Simulation is slooooow (try Runge Kutta 4th order).

    No ps or eps or pdf graphics. It's not serious!

    The only choice to export results is Excel but the resulting .xls file makes open office hang.

    Simgua crashes continually. Amateurish work.

    $860.0: is this price a joke!
