# Simulating a Trace

By simulating a trace, the raw traces previously imported and/or acquired are processed in order to generate the trace that the STbench will simulate during the test.

1. On the upper-right corner of the Raw category, tap Select.

2. Select the check box of the traces to include in the simulation.

3. On the upper-right corner of the Raw category, tap Process.

4. In the Simulation category it is possible to:

   - adjust the Polynomial fit (by default set to 7)

   - adjust the Start projection (by default set to 5%)

   - adjust the End projection (by default set to 5%)

   - show/hide raw traces (by default enabled)

   - show/hide average trace (by default enabled)

   - align the raw traces with the torque peak (by default enabled)

5. Tap the Test button to test the simulated trace.
   The trace is sent to the STbench and the test starts on one of the brakes. In this way, it is possible to evaluate the quality of the trace approximation and to verify that the test can be run.

   The software does not automatically select the brake based on the curve and the brake capacity. Make sure to select the most suitable brake to run the test.

   In the Simulation test screen it is possible to acquire up to 10 test traces (from the eleventh onwards, the oldest traces are progressively deleted).
   By clicking on the Align at the torque peak button () the curve to simulate and the simulated ones are aligned at the torque peak.

6. Exit the Simulation test screen and then tap Save to save the parameters of the simulated trace.
