Intalledges command and reduced order model

General Discussion
1

Dear FF++ users,

I would to ask please two separately questions ,

  1. In which case (or cases) should one use the “intalledges” command rather than the “int1d” command?

  2. Are there any libraries in FF++ that are dedicated to reduced order model techniques for dynamic problems? if yes, could you please name some of them?

Thanks in advance,

Mordechai.
