Using STAR-CCM+ v12.02’s new ray-tracing capabilities, engineers can create photorealistic renderings of design and simulation results. Applicable to all flamelet combustion models, the company says, adaptive gridding can reduce table size and corresponding memory usage by up to 30 times, increasing efficiency and allowing engineers to iterate designs more quickly. According to Siemens, the software’s new Adaptive Gridding capability for combustion tables significantly reduces computational effort without any loss of accuracy. STAR-CCM+ v12.02 adds capabilities to accelerate simulation throughput for products that deal with reacting flows, such as furnaces, reformers, internal combustion engines and gas turbines.

An earlier version of STAR-CCM+ created a 1.16GB table of the same model in 19 minutes. In this example of carbon monoxide in gas turbine combustor, v12.02 required 5 minutes to generate a 128MB combustion table. STAR-CCM+‘s new adaptive gridding feature increases the accuracy of a combustion table in less time while keeping the table size at a minimum, according to Siemens.
