Multiphysics Simulations are key to understanding the simultaneous effects of various domains on a structure and to obtaining an accurate assessment of the loading and its coupled influence on the structure. In Aerospace, while dealing with Hypersonic Vehicle Structures, it is critical to correctly understand and simulate the multi-physics nature of the problem involving– aerodynamic loads, high temperature loads and acoustic loads. One great example – from ATA Engineering -- is the simulation of a representative Hypersonic Vehicle Structure utilizing the Co-simulation Engine (CSE) capability in Abaqus coupling a CFD code Loci/CHEM and Abaqus. I highly recommend that you watch this three-part Video explaining the methodology behind this co-simulation problem. I hope you enjoy this presentation as much as I did!

Part 1: Introduction and Technical Approach:
- Motivation
- Multiphysics Problem Set-up using Abaqus Co-simulation Engine
Part 2: Details of the workflow:
- Glass and Hunt validation Case
- Multiphysics Panel Simulation on Notional Hypersonic Vehicle
- Aerothermoelastic Solution Procedure Details
Part 3: Results, Conclusions and Outlook:
- Effects of local deformation on shock structure and creation of local Flow
- Conclusions
The video ends with a conclusion that drives home the points that multiphysics planning should begin early in the design process and that understanding of each displine’s modeling assumptions/abstractions is crucial when reconciling models for co-simulation.
Enjoy!
