Is it possible to use Create>Results for creating a new result case from two existing results case, so that the new result contains values produced by multiplication or division of the existing results? Something like Results>Combine, only that the Combine tool can only create linear combination of existing results, and I need multiplication and division. I thought Results->PCL Function could help, since it allows selecting multiple existing result cases, but I do not see how to identify a particular case when entering a PCL formula.
You can't do this in the standard results tool, but you should be able to get what you want using Utilities/Results/Results Toolbox. This allows you load results into various registers, then create new results based on mathematical operations with those registers.
