Illinois Rocstar Awarded $1M DOE Phase II SBIR to Develop Computational Chemistry Dataset Storage Solution

Illinois Rocstar has been awarded a DOE Phase II SBIR project entitled, “The Chemlab Chemistry and Materials Science Lifecycle Data Repository.” The Chemlab project is designed to not only provide a place for scientists and engineers to archive and document their simulation datasets, including provenance information and output data, but to offer a location to share and find datasets again later.

Illinois Rocstar Announces a New DOE SBIR Phase I Project, NEMoSys: A Platform for Autonomous Mesh Refinement and Solution Verification

Nuclear reactors, whether Light Water Reactors (LWRs) or liquid metal cooled fast reactors, are complex machines requiring detailed design in complex multiphysics scenarios. Modeling and simulation (M&S) are key elements in the design and advanced safety modeling of nuclear reactors. In this Phase I SBIR project, Illinois Rocstar plans to extend our NEMoSys meshing package to support autonomous adaptive mesh refinement and solution verification to better serve the needs of the nuclear energy M&S community.

Illinois Rocstar Celebrates 10 Years!

This year marks the tenth anniversary of Illinois Rocstar LLC. In June of 2007, five researchers working together at the University of Illinois at Urbana-Champaign (UIUC) Center for Simulation of Advanced Rockets (CSAR) decided to form a company to give new life to the UIUC Rocstar Simulation Suite (Rocstar). Rocstar was developed under DOE funding over 10 years at CSAR. Illinois Rocstar LLC, the product of that decision, has gone on not only to upgrade the original Rocstar into the current open-source Rocstar Multiphysics toolset, but to perform work in many other areas of Computational Science and Engineering.

Modeling Supercritical CO2

Illinois Rocstar is excited to announce a partnership with Sandia National Laboratories on a new SBIR contract entitled, “PIV-Validated RANS Turbulence Modeling for Buoyant Supercritical CO2 Flows.” The goal of this project is to develop a cost-effective turbulence model specifically designed for supercritical CO2 flows in direct-fired Brayton cycles.

Going beyond convention.


Illinois Rocstar does simulation science; we build the tools, the infrastructures, and the interfaces to help industry gain a return on their investment for using modeling & simulation to improve their processes and products. From macroscale multiphysics that couple fluids, solid mechanics, materials, and chemistry to microscale crystal-level modeling of a variety of granular materials, Illinois Rocstar has tools to help address these areas. Using our open-source Illinois Rocstar Multiphysics Application Coupling Toolkit, developers can build new multiphysics, multiscale applications from open-source or proprietary codes in fractions of the time it would have required previously. We apply the right tools for solving modeling and simulation problems relevant to industry, government, and academia.
