Running a simulation

Running a simulation

To start a simulation, select the menu item Tools | Run or the Run button  in the toolbar. The system’s views may also contain a button for this purpose.

The algorithm of the Run command may include checking the parameters and connections, building the mathematical model (for wizard and the physical levels). If some problems occur at that time, they will be reported in the log window and the simulation will be suppressed.

The IDA Modeler prepares the IDA input file and calls the IDA Solver. During a simulation, a monitor window is displayed. It shows the execution time, current solver activity, and the values of up to 3 variables.

After a successful simulation, IDA Modeler reads the results of the simulation and prepares the reports.

If the simulation failed, a text document may be opened containing error messages that can be used to find the reason for the failure. A common reason for failure is that the simulated system does not constitute a well-posed problem.

IDA applications may support multiple types of simulations.
