- Simulation
  Learn how to set up, run, and troubleshoot simulations.
  - Set Simulation Parameters
    Before executing a simulation, you can define parameters for simulation time, zero-crossing and solvers.
  - Create a Results File
    Capture and review simulation results including the signals of all blocks in a model.
  - Run a Simulation
    Execute a simulation with the Run tool on the ribbon.
  - View Results
    Discover options to review, display, and export results.
  - Troubleshoot
    Learn troubleshooting techniques for common simulation issues.
  - Debugger
    The Twin Activate debugger is an interface that lets you control the advancement of a simulation so that, at every pause, you can inspect and modify block objects, which includes model signals.
  - Functional Mock-Up Interface Support
    The Functional Mock-Up Interface (FMI) is an emerging standard for creating interfaces between different tools.
  - Simulation Phases
    The process of simulating a model occurs in three phases: Evaluation, Compilation and Simulation. The Evaluation and Compilation phases occur first and generate a structure that is processed during the Simulation phase.

OML Editor

The OML editor is used to create, edit, and execute OML scripts.

The editor is also used in model and diagram context, but unlike them, the code is not executed automatically. To execute the script, click the Run button.
