Altair Flow Simulator™

Integrated Fluid, Heat Transfer, and Combustion Design Software

Flow Simulator is 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 computer aided design (CAD) point-cloud to automatically create the computational model overlaid on the machine hardware. An extended library of preconfigured elements/components is available to model/simulate a wide-range of physical phenomena including compressible/incompressible fluid flow, buoyancy-driven flow, rotating cavity system flow, conduction/convection/radiation heat transfer, combustion equilibrium-chemistry, and species transport. Eight combinations of analysis modes (steady state, quasi steady state, and transient analysis for fluid dynamics, thermal, and combustions) are available to predict system/subsystem run conditions during a cycle/mission simulation (flight mission, power ramp up, shut down…etc). Control system components (proportional integral derivative (PID) controllers, feedforward, and mission) can be integrated with computational model system/subsystem to optimize the simulated-machine operation during cycle/mission analysis.
