Innovators at NASA’s Johnson Space Center have developed software that is an easy-to-use implementation of the Direct Simulation Monte Carlo (DSMC) method that can be applied to a broad base of low-density flow problems. DSMC is the de facto standard for predicting low-density flows because the continuum-based equations used by traditional computational fluid dynamics codes are invalid in rarefied conditions. The DSMC Analysis Code (DAC) software features surface modeling components that allow users to model complex geometries and boundary conditions quickly and easily. Its built-in flexibility, automation, and intuitiveness, combined with the potential of its parallel processing capabilities, provides an easy-to-use, high-performance solution for analyzing rarefied flows. This software may be released to U.S. persons only.
This technology is being made available through JSC’s Technology Transfer and Commercialization Office, which seeks to transfer technology into and out of NASA to benefit the space program and U.S. industry. NASA invites companies to consider licensing this technology for commercial applications.
