An exploration is a multi-run simulation. Each exploration includes input design variables, and output responses.
Explorations may also include goals, consisting of an objective and constraints.
An input design variable is a system parameter that influences the system performance in the chosen output response.
Typical design variables may be a part's thickness, shape, or material property. Ranges, with lower and upper bounds,
are specified and the variable's value will vary within the exploration. The terms input, input design variable, and
design variable are used interchangeably.
Constraints need to be satisfied for an optimization to be acceptable. Constraints may also be associated with a DOE.
While not used in the evaluation of the DOE, constraints can be useful while visualizing DOE results. Limits on displacement
or stress are common examples.
