Running a Model

Selecting Run | Run Model, pressing F5, or pressing the Run button in the Run Control toolbar causes GoldSim to check the model for errors (to see if it can be run).

The second button from the left in the Run Control toolbar is the Run button.

If an error is found in the model such that it cannot be run, GoldSim will display a fatal error message describing the problem. In most cases, a button on the dialog displaying the error message will allow you to jump directly to the element causing the problem.

If GoldSim does not detect any errors, the model will be placed into Run Mode The state of a model when it is running. and the simulation will begin. While the model is running, the status bar A bar at the bottom of the GoldSim interface that provides information regarding the status of the model. will display the status of the run (i.e., current realization A single model run within a Monte Carlo simulation. It represents one possible path the system could follow through time., timestep A discrete interval of time used in dynamic simulations., and elapsed time).

In addition to running the model, the Run Control toolbar can also be used to pause and resume a simulation, and/or step through the simulation one timestep or one realization at a time.

A small dialog will alert you when the simulation is complete:

Clicking the OK button in this dialog (the only button) will place the model into Result Mode The state of a model when it has been run and contains simulation results for a single set of input parameters..

If there were any warning messages generated during the simulation, you will immediately be given an opportunity to view the Run Log Text that is stored with a GoldSim model once it has been run. It contains basic information regarding the simulation, and any warning or error messages that were generated.. The Run Log contains basic statistics regarding the simulation (e.g., the version of the program, the date, the simulation length), and any warning or error messages that were generated.
