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

August, 2017

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

August, 2017

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!

June, 2017

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.
