How does GoldSim represent time in a model?
GoldSim is a dynamic simulator. As such, the objects used to build a model inherently understand the concept of time. For example, some objects represent integrals over time; others represent delays. You can also write equations that are a direct function of time: e.g., “if(Time > 1 yr, X, Y)”. When you build a GoldSim model, you specify the duration of the simulation and the number of timesteps (i.e., the degree to which you want to discretize time). GoldSim then steps through time, allowing variables to evolve and change through simulated time. GoldSim also provides powerful tools for controlling the timestep length dynamically to ensure accurate solutions.
