Our Flagship Product

FlightStream

FlightStream® is a panel methods aerodynamic solver designed to allow users to analyze a variery of different flow problems with a modernized GUI. Aircraft design is a big part of what we do, but applications range from aerospace, to automotive, to turbomachinery, and more!

Included with FlightStream are popular toolboxes such as Solver Sweeper, Stability & Control, and API scripting to provide powerful batch process capabilites to rapidly estimate aircraft performance.

Integrated Workflow

An all-in-one simulation platform, FlightStream® allows you to manage all steps of the aerodynamic analysis process in one place. Simplifying your workflow and saving you time!

FlightStream is a Team Player

FlightStream® seamlessly integrates with a wide range of CAD/CAE tools, including favorites like NX and SolidWorks, supporting various file formats such as STL, STP, and IGS for versatile import options. It can also handle direct mesh import from tools like Cadence Pointwise® and ANSA as an STL.

Additionally, FlightStream® boasts export capabilities, allowing users to transfer solution resultsTecplot 10, Tecplot 360, ParaView, using the VTK file format.

For those involved in structural analysis, FlightStream® can export detailed aerodynamic force or pressure distributions, ensuring smooth workflow integration with leading software such as Abaqus and MSC Nastran.

Release Notes

Released 12/8/2023

Flagship Enhancements

Revamped S&C toolbox that allows massive new flexibility with user-defined static and dynamic stability coefficient computations. Parametrized coefficients, custom coordinate systems, boundary lists and more. Fully scriptable and automated!

Unsteady Solver Enhancements

  • 6DOF motion definition has ability to specify initial conditions and to create constrained motions. New applications enabled by these features include autorotations, 3DOF stability and vehicle response analysis
  • Wake termination node by time steps instead of truncation by plane only. This powerful feature allows simulation of viscous vortex decay in very low advance-ratio (and hover) simulations and allows robust modeling of hovering rotors and propellers

General Solver Enhancements

  • Flow separation models can be specified by boundary, enabling both models to be applied on specific boundaries within the same simulation runs
  • Toggle to enable pure inviscid loads and moments in addition to default decoupled-viscous and viscous-coupled simulation modes
  • Toggle to enable wake relaxation modes

Geometry Pre-processing Enhancements

  • CCS file format supports advanced flap and high-lift device modeling with new abilities to model slots, gaps and flap leading edges
  • Simplified CCS control surface settings reduce user overhead and inputs
  • CAD improvements – New: CAD Create–>CCS format tools and performance improvements

UI Enhancements

  • Plots mean value function allows selection of individual plots for data processing

Miscellaneous

  • FlightStream Youtube Channel with 20+ training videos, tutorial simulations and more
  • Enhanced User Guide with several new best-practices topics
  • Enhanced scripting API for all new features described above
  • Several bug fixes

Hardware Requirements

Minimum

  • OS: Windows 7, 10, 11 or later (64bit)
  • Free Hard-Disk Space: 100 MB (More space is required to save simulations)
  • RAM: 8 GB
  • Dual-core processors or better
  • Dedicated graphics card

Reccomended

  • Free Hard-Disk Space: 1 GB (More space may be required to save large simulations)
  • RAM: 32 GB (Higher memory may be needed for large simulations)
  • 8-24 cores for parallel scaling of the solver
  • Intel i7/i9 processor (or equivalent)
  • Nvidia GPU graphics card (or equivalent)
  • Integrated graphics chipsets are not recommended.
