Fluid flow/heat transfer CFD package updated

December 18, 2015 // By Graham Prophet
Mentor Graphics has a new release of its FloEFD computational fluid dynamics product that offers improved accuracy and user productivity. Updated features in this new version include improved mesh handling, an enhanced transient solver, a robust EDA interface, and an interface to Abaqus Finite Element Analysis (FEA) software for stress analysis.

The package targets engineers and specialists across the automotive, aerospace and electronics markets. The latest version of the FloEFD product offers new capabilities for minimising user time and effort spent on meshing. The FloEFD tool can automatically fill gaps of specified size to quickly make the model watertight, thereby eliminating the time and necessity to adjust the original geometry. An equidistant refinement capability lets users build multilevel uniform meshes around the body or surface of the model with just one click. And the mesh preview visualisation tool helps users achieve the desired mesh with ease and speed.

The FloEFD product release also features the following:

• A highly improved transient solver allows for faster solution of transient applications as well as higher accuracy for pressure-dominated tasks such as calculating filling/evacuating of a tank or water hammer thereby increasing range of realistic situations that can be modelled.

• A powerful electronic design automation (EDA) interface can help users avoid creating PCBs manually. Users can now import geometric EDA data including copper traces and vias. The interface supports the Mentor Graphics Xpedition (CC or CCE), IDF and OCB++ PCB design data formats.

• The refractive index depending on wavelength and temperature offers higher accuracy of light and radiation analysis in case materials with complex spectral characteristics are utilised e.g. in automotive lighting industry.

• The ability to visualise rays used for precise radiation modelling allows the user to better understand the impact of the sources on the system, thus helping to find the reason of overheating and suggest the solution faster.

• An engineering task usually requires views from different angles. To support multi-disciplinary analysis, the FloEFD tool can now export pressure and thermal loads to Abaqus for further stress analysis.

• The Calculation Manager displays all projects currently running and those in the queue, thus allowing users to get a better idea as to where their projects stand and to easily control all calculations running at the moment.
