The DARS simulation toolkit is the main product developed by DigAnaRS the joint venture between LOGE AB and CD adapco. DARS (or Digital Analysis of Reaction Systems) is a tool that enables the analysis of complex chemistry in engineering applications. It includes many chemical kinetic models tailored for specific conditions and for particular chemical species, and handles both gas phase chemistry, surface chemistry and soot modeling. DARS includes several reactor tools for use with the chemical models. DARS is fully integrated with both STAR-CD and STAR-CCM+, and can be used with any other CFD simulation tool.
