What is the purpose of result classes?
There are usually lots of combinations generated in your project to cover all extreme values. Some of these combinations serve just as a sub-combinations for envelopes, or we want to exclude them to speed up our design process in a specific range. Result class list defines the combination range to be considered for the checks.
We will show it in the example, where we will exclude the sub-combinations,
or just the combinations for the last stage.
