CFD models enable the realistic simulation of complex flow phenomena and with that a cost effective proof of functionality. At the same time, enhanced visualizations of simulation results increase the understanding of the complex processes. Due to the flexible adaptability of numerical models, systems can be easily optimized and improved. This leads to a reduction of construction errors while maximizing the benefit.
