Run parameters Best Practices

You can improve simulation runs by adjusting tolerance, maximum time steps, and solver types.

• Tolerance: The smaller you set the tolerance, the more accurate your results will be. Normally, tolerance should be in the range 1.0e-10 to 1.0e-3. Consider reducing the tolerance when the run does not converge.

• Maximum time step: The default value is 1.0e30, which is correct for most runs. However, occasionally Simcenter Amesim Run takes too large steps, producing strange results. In such circumstances, you should reduce this value.

• Solver type: Using Cautious ensures that the maximum time step is limited to the value of the print interval.
