Mentor Graphics launches FloEFD software with sliding mesh, water film, and improved radiation capabilities

Mentor Graphics Corp. has announced the latest release of FloEFD, its computational fluid dynamics (CFD) software. The new release provides advanced capabilities and functions that let designers and analysts create more realistic operating environments and models for improved simulation accuracy.  New features include a sliding mesh model for rotating equipment such as pumps, fans, and blowers; water film simulation to calculate surface condensation and icing film thickness; together with radiation and lighting enhancements. These new capabilities support automotive industry initiatives for developing state of the art lighting products as well as enabling manufacturers to design better pumps, fans and blowers.

The FloEFD product is a leading general-purpose CFD software solution for the mechanical design market, and the new enhancements were developed to help engineers create more accurate simulation environments for their products.  New key features include:

  • Sliding mesh modeling which lets users create more realistic simulation of rotating equipment when fluid quantity is highly non-uniform around a rotating part (such as a pump or fan) and cannot otherwise be calculated with circumferential averaging.
  • Surface condensation and evaporation, the new water film model, is valuable for situations where surface condensation, evaporation, icing and de-icing exploration is essential, such as condensation on the inner surfaces.
  • Enhanced radiation modeling: The new ray-based (band-less) spectral model for lighting and radiation lets users significantly decrease time required for defining wavelength-dependent properties while increasing simulation accuracy of spectral characteristics. Gaussian surface reflection for more precise simulation of reflected radiation is also included. Inclination of solar rays from the parallel can now be taken into account too thus allowing capture of solar radiation in greater detail.
