CFdesign is also integrated with Pro/ENGINEER® and works associatively with native 3D geometry produced in any MCAD system that employs ACIS, Granite, or Parasolid modeling kernels.

When a single drop of fuel can decide the winner of a vehicle economy competition, excellent aerodynamics is critical. That is what we realized at the Department of Mechanical Engineering of the University of Coimbra when we decided to enter the annual Shell Éco-Marathon contest in 1998.

In this event, each prototype must cover six laps of the Nogaro circuit, at a minimum average speed of 25 km/h with only gasoline, diesel or LPG as permitted fuels. The volume of fuel spent is then measured and an extrapolation is made for the distance the car would travel with one liter of fuel. With the overall drag of a vehicle being determined by the small difference between positive and negative forces, numerical prediction is very sensitive to the accuracy of the numerics. Flow separation can compound these difficulties, though in our case, the car shape was designed to avoid any separation.

Due to the large range of feature size in a typical boiler (which include hundreds of tubes), unstructured meshing is usually prohibitive. Often, meshing is the bottleneck in boiler design. SoftInWay's parameterized boiler mesh generator makes mesh study and design optimization much easier, saving customers time and money.

The mesh generator creates an input file for a customer-specified solver, such as COSMOS, ANSYS, NASTRAN, Fluent, etc.

The User-Meeting will concentrate on advanced simulation and design-optimization technology specific to turbomachinery. However, there will also be important sessions on unstructured solution-adaptive simulation for aerospace, automotive and other applications. The new unstructured CFD suite FINE/HEXA, which employs efficient solution-adaptive grid-refinement/coarsening based on purely hexahedral grids, will be unveiled. Although HEXA/NS is only now being released, it has already been used in large-scale consulting studies and consortium projects concentrating on such topics as DES and aero-acoustics simulation.

K-Epsilon now....
then something far more complex!
Does it matter much?

Previously, the firm’s engineers found that applications designed in-house to solve specific problems were difficult to use, mainly because the applications only offered a DOS command line interface. However, this limitation has now been overcome. “The subject matter experts themselves used EASA to wrap GUIs around these applications, making it possible for far more engineers to take advantage of the time savings they provide,” said Denny Hayek, Process Engineering Manager for Monsanto.
