Altair FlightStream

FlightStream reduces computational requirements by focusing on the most critical aspects of the flow, such as the behavior near surfaces and in regions of high aerodynamic interest. This targeted approach reduces the number of calculations needed compared to solvers that attempt to model every aspect of the flow in detail. Key aspects include surface mesh discretization to focus only on the objects surface and adaptive meshing to apply finer meshes only to areas of importance.

A powerful set of solvers designed to address the diverse aerodynamic challenges faced in the aerospace, maritime, turbomachinery, and wind energy industries. Its solver capabilities include advanced methods like the Panel Method and Vortex Lattice Method for efficient inviscid flow simulations, the Viscous-Inviscid Interaction (VII) solver for accurate boundary layer and flow separation analysis, and a Compressible Flow solver for high-speed applications where shock waves and compressibility effects are critical. Additionally, the Unsteady Aerodynamics solver captures time-dependent phenomena, making it invaluable for analyzing dynamic conditions such as rotorcraft blade movement and transient events in wind turbines.

FlightStream integrates with a wide range of other engineering tools, enhancing its versatility and enabling a more comprehensive design and analysis workflow. Its ability to connect with Altair’s broader suite of products, such as HyperMesh for pre-processing and OptiStruct/Radioss for structural analysis, allows engineers to perform multidisciplinary optimization and ensure that all aspects of a design are considered. With the Altair Units licensing model, users also get access to all of these co-simulation tools without the high individual cost.
