Select a Numerical Method

Select a numerical method to use when evaluating run data from the study Setup.

1. In the Specifications step, Mode column, select a numerical method.

   Option	Description
   Nominal Run	Runs one simulation, and sets the input variable's values to the initial values.
   System Bound Check	Checks the study setup and the design space using three runs. The first run sets all of the input variables to their nominal values, the second run sets all of the values to their lower bounds, and the third run sets all of the values to their upper bounds.
   Sweep	Evaluates design alternatives for a study where the input variable values increase in equal increments. For example, the first run sets the input variables' values to their lower bounds, the last run sets the input variables' values to their upper bounds, and the runs in between will be set at equispaced incremental values that are determined by the number of runs you specified. By default, five simulations are ran. The values for a discrete input variable are iterated by index. If the number of runs exceeds the maximum index of the discrete list, the indexing scheme returns to the first index in a periodic sense.

2. Optional: In the Settings tab, edit the number of runs.
3. Click Apply.
   A run matrix is generated using the numerical method you selected.
