An analysis envelope is a stored envelope of results produced in way similar to other analysis options. I.e Analysis envelopes are requested by setting up an appropriate analysis task via the Analysis Wizard and then analysing this. The envelope is produced by comparing results from cases described in the syntax of a standard enveloping combination case. Since it is stored it is very much quicker to display than the alternative combination envelope that is produced by examining all effected analysis case results at the time of display. The disadvantage of analysis envelopes is that derivation of other results from those stored is not possible.

Most results produced by GSA can be enveloped. A result envelope is the worst (maximum and minimum) results encountered in a series of analysis or combination cases. Result envelopes are produced for enveloping combination cases.

Combination cases may be used to combine the factored results of a number of analysis and combination cases. They may also be used to identify a number of permutations of factored cases for the enveloping of results. The former are referred to as simple combination cases and the latter as enveloping combination cases.
