Computational fluid dynamics (CFD) has emerged as a third pillar of the fluid mechanics field, joining analytical and experimental studies. When appropriately combined with experimental validation, the highly detailed solutions…

The OPTImat© system (Optimization of Materials) is designed to bring cloud-based tools and techniques to materials and chemistry simulation scientists for performing sensitivity, uncertainty quantification, and optimization studies in the cloud.

Illinois Rocstar was founded in 2007 with the goal of advancing high-fidelity modeling and simulation (M&S) of solid propellant rockets. Although the company has substantially broadened its business horizon over the past decade, we have never abandoned the technology needs of warfighters. Throughout the past three years, Illinois Rocstar has refined its focus on weaponeering to support the U.S. Air Force and Navy in their M&S applications.

As energy appetites around the world continue to grow, hydrocarbon fuels will continue contributing to the energy portfolio for the foreseeable future. At the same time, concerns about climate change have increasingly motivated development of energy sources that contribute less to atmospheric carbon levels. Use of supercritical carbon dioxide (sCO₂) in modern power cycles has grown in recent years, since the carbon dioxide-rich fluid allows for improved thermodynamic efficiency, more compact facilities, and impressive reductions in cost compared to supercritical steam cycles. As a result, sCO₂ power cycles have seen increased evaluation for deployment in a variety of applications, including the complex process of combustion.

When designing a new material or studying the interaction between materials, the ability to minimize or maximize system properties is often vital to improving the material’s properties. The OPTImat (Optimization of Materials) system will be applicable to broad ranges of problems for which the chemical and materials modeling techniques that will be available to the system can be applied.

Illinois Rocstar is excited to announce a contract to continue development of the NEMoSys© toolkit for autonomous mesh refinement and solution verification. Modeling and simulation (M&S) are critical for cost-effective…

This new contract with the U.S. Department of Energy aims to develop accessible, efficient reduced order model software to advance the goals of major modeling and simulation initiatives. The workflow envisioned will enable users to generate parameterized proper orthogonal decomposition (POD) bases from high fidelity computational fluid dynamics (CFD) simulations. The novel parameterization technique employed by this technology will address stability concerns often associated with POD while assisting users in successful production of fast running models with large eddy simulation (LES) quality.

The Lethality Impact Maritime Analysis (LIMA) toolkit to be developed by Illinois Rocstar received funding from the United States Department of Defense this week.

Illinois Rocstar developers are working to release a new version of Rocstar Multiphysics as both an open-source application and a cloud-ready, high performance computing service on our Simverse platform (http://simverse.com). (more…)

Illinois Rocstar has been awarded a contract 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.
