We work with old xdb results files, where one result file corresponds to a single load case. There are over 50 of these, and currently the only way I know to add them to the .db is via Analysis > Access Results > Attach XDB > Select Results File > *select file* > Apply
This is really cumbersome and slow, since I can only do this one file at a time. Is there a way to force it to let me access all of them at once? Shift or CTRL clicks don't seem to work within the Patran UI. I'm using Patran 2021.2.
There's actually a SimCompanion article with an attached PCL script and accompanying instructions that will allow you to attach multiple XDB all at once.
