# Conducting a model execution

Once your dataset has been properly uploaded, edited and reviewed, you can proceed to conduct a simulation. This page outlines the steps for launching a model run from the Pharoes platform.

## Step-by-Step Guide

1. **Open the "Runs" Tab**
Inside your project view, navigate to the **Runs** tab. This is where all previous and ongoing simulations are listed.

2. **Click on "Start Run"**
Click the **Start Run** button to initiate a new model execution.

3. **Fill in the Run Configuration**
A form will appear where you need to specify the parameters for the simulation:
  * **Run name**: A user-defined name to identify the run (e.g., *"Baseline scenario – June 2025"*).
  * **Execution**: Choose the execution configuration to apply (e.g., solver version, hardware settings).
  * **Max. time**: The time limit (in minutes) for the solver to run before finishing.
  * **Tolerance**: Define the acceptable solution gap (e.g., 0.0002 for 0.02%) to balance speed and accuracy.
  * **Initialize using run**: Optionally, select a previous execution to warm-start the simulation. This can speed up convergence for similar runs.

4. **Click "Start Run"**
Once all parameters are configured, click **Start Run** to launch the model execution.

5. **Wait for Completion**
The run will begin processing. Depending on model size and configuration, this may take a few minutes. Please wait until the run reaches **finalized** status before attempting to view results.

## Notes

* While the run is in progress, the status will be displayed in the **Runs** list.
* If the run fails, an error message will be shown. You can inspect the logs for debugging.
* Once the run completes, output results and performance metrics will be available for review and download.
