-The simulation section will display simulation progress as well as errors that need to be resolved before a simulation can be performed. The {{:RunAll16.png}} button will start a simulation, and the {{:Stop16.png}} button will stop an ongoing simulation. The progress bar will show you how far the simulation has progressed. For deterministic simulations it will display the current time point, and for probabilistic simulations it will show the current iteration.+The simulation section will display simulation progress as well as errors that need to be resolved before a simulation can be performed.

   * **Time series** – This field is only available when the output option is set to either ‘Produce additional output’ or ‘Produce specified output’. To create a time series click the **Add** button. From the window that appears select the type of time series you want to create using the drop-down list. You can add as many time series as you want. However, the possibility to add more than one time series is typically only used when you wish to combine a linear/geometric time series with some custom time points. To remove a time series just click the time series to be deleted and click the **Remove** button.   * **Time series** – This field is only available when the output option is set to either ‘Produce additional output’ or ‘Produce specified output’.

 The output page lets you choose simulation endpoints. All blocks of the project are displayed and are organized by sub-system. By selecting/unselecting either endpoints or whole sub-system nodes, you determine which simulation outputs will be available after the simulation is finished. The output page lets you choose simulation endpoints.

 **Absolute tolerance** - Absolute error tolerances that apply to the individual components of the solution vector. Absolute tolerance is a threshold value below which the value of the solution component is unimportant. The absolute error tolerances determine the accuracy when the solution approaches zero. **Absolute tolerance** - Absolute error tolerances that apply to the individual components of the solution vector.

 **Relative tolerance** - Relative error tolerance that applies to all components of the solution vector y. This tolerance is a measure of the error relative to the size of each solution component. Roughly, it controls the number of correct digits in all solution components, except those smaller than thresholds defined in Absolute tolerance. The default, 1e-3, corresponds to 0.1% accuracy. **Relative tolerance** - Relative error tolerance that applies to all components of the solution vector y.
