Science in the code.

Rocstar Multiphysics is designed to conquer engineering problems of large scale. Rocstar™ is engineered for the fields of solid propellant rocket and missile design, multiphysics-dependent engineering and manufacturing simulations, and other highly complex, high-performance applications. Including state-of-the-art physics modules and coupling algorithms, Rocstar Multiphysics targets users who need ironclad solutions to high-cost, time-intensive problems that require extensive computational capability.

Rocstar™ has been architected from the ground-up to be a massively parallel simulation suite and stands ready to leverage the high-performance-computing resources of the future. It is routinely used on hundreds to thousands of processors, and has successfully performed simulations on over 50,000 cores. Rocstar Multiphysics© offers a software integration and multiphysics coupling framework that interfaces with models and software packages that leverage your scientific and engineering expertise. Rocstar Multiphysics runs on hardware from large engineering workstations to some of the biggest supercomputers in the world.

Rocstar Multiphysics contains modules and support for:

  • Advanced computational fluid dynamics
  • Structured multiblock and unstructured mixed-mesh codes
  • Computational solid mechanics
  • Several solid propellant burn-rate models
  • Sophisticated integration infrastructure to allow multiphyiscs modeling
  • Conservative and accurate mesh-to-mesh data transfer
  • Regressing surface models, including mesh motion and smoothing
  • Many general compressible fluid-dynamics, fluid structure interaction, and fluid-structural-thermal problems

Who needs Rocstar Multiphysics?

Rocstar Multiphysics™ is designed to support scientists and engineers with enormously complex problems that require multi-million-dollar hardware—working long stretches at full steam—to simulate. Rocstar™ targets massively parallel platforms and has been run on some of the largest machines in the world. However, it also has application on multicore workstations for smaller problems. Applications extend across the U.S. military branches, Department of Defense, Missile Defense Agency, NASA, aeronautics companies and manufacturers, and any agency—academic, public or private—that needs to cut expenses while their R&D soars ahead of the pack.

The future of Rocstar Multiphysics

Developers at Illinois Rocstar are working on releasing a new version of Rocstar Multiphysics™ as both an open-source application and a cloud-ready, high performance computing service on our Simverse™ platform. The new framework will offer both software integration and multiphysics coupling to interface with models and software packages. This effort is focused on making updates to and web-enabling Rocstar Multiphysics™ to produce new capabilities that are both easy to use and openly available. The new web-enabled graphical interface will bring Rocstar Multiphysics™ to the forefront of scientific simulation tools. Once the capabilities have been added, a full interface created, and ease of installation and use are improved, Rocstar Multiphysics™ will help lower the entry barriers to high performance computing-based modeling and simulation encountered when attempting to use existing software. These modernization efforts will make available use of remote high performance computing facilities through the Illinois Rocstar Simverse™ environment.
