Information

This information is part of the Business Simulation Library (BSL). Please support this work and ► donate.

This is the general, unrestricted reservoir of the system dynamics methodology, it accumulates information transported by flow components connected to the StockPorts. The InformationLevel can become negative.

Notes

• The inflow and outflow →StockPorts are only indicative; in general the reservoir may be filled or drained by flows connected to either port.


• The parameters maxValue and minValue allow to define an admissable range. It can be monitored by an assert using useAssert = true in the Advanced tab. The switch causeError controls whether an error or a warning is to be raised.


• The parameter init in the Advanced tab allows to select →InitializationOptions:
  
  
  • FixedValue (default) will use the parameter initialValue to determine the initial value.
  
  
  • SteadyState will introduce the equation der(x) = 0 in order to find an initial value that establishes equilibrium.
    (Note: Such a solution may not exist and to avoid trivial solution in many cases initialValue -- in this case used as a start value for numerical iteration -- should be set to a value different from zero.)
  
  
  • Free there will be no initial equation and thus the solver is free in solving the initial value problem.

• There is an optional →StockInfoOutput connector.
