Description
Sandia's SIERRA Thermal/Fluid Development Team issued this user manual, SAND2026-16588, printed January 28, 2026. Its subject is Arpeggio, the coupling module for the Sierra Mechanics suite. Sierra's applications each simulate one physics well. Real problems couple several at once. Arpeggio provides loose coupling between the applications. It gives them access to shared framework services, and it orchestrates their joint execution. Analysts use it to run, for example, a thermal code and a fluids code as one scenario.
The manual describes Arpeggio's components and how they operate. Command reference entries fill most of the book: assigning start times, suppressing output from the nonlinear loop, setting termination times. Simple examples lead, so a new analyst can reach a working coupled run quickly. Version 5.28 is the release documented. For multiphysics teams, Arpeggio is the conductor, and this manual is its score.
