An introductory webinar to Flow Simulator, an integrated flow, heat transfer, and combustion design software that enables mixed fidelity simulations to optimize machine and systems design. This fluid system design tool provides interdisciplinary modeling and optimization capabilities within a single platform for machine design with respect to fluid dynamics/thermal/combustion within a 3D design environment. This tool allows users to import actual hardware and utilization of 3D CAD point-cloud to automatically create the computational model overlaid on the machine hardware.
