Description
Sandia National Laboratories manual SAND2026-21786, by Samuel Subia, James Overfelt, and David Baur, documents Arpeggio version 5.30, the coupling module for the Sierra mechanics code suite. Sierra's specialized applications each solve part of a multiphysics problem. Arpeggio passes data between them. A thermal code and a structural code can then advance together instead of in separate runs stitched by hand.
The manual is a command-by-command reference. Time step controls get detailed treatment. Steps can clip or overrun at a transient loop's end. A snap option quantizes time values to multiples of a quantum 12 orders of magnitude below the loop span. Defaults are stated for every parameter. Analysts coupling Sierra applications consult it to configure runs that stay synchronized.
