STAR-CCM+ is being used in conjunction with CRTech's Thermal Desktop to solve multidisciplinary problems. CRTech and CD-adapco™ will demonstrate how these complementary codes have been used together in the past, and how new interfaces under development will make using Thermal Desktop and STAR-CCM+ together easier. The new features include co-simulation using the STAR-CCM+ Co-Simulation API, as well as improved interfaces for sequential simulations.
