Group aims for wider acceptance of CFD

One reason CFD finds limited use in product design is the effort required to clean up CAD geometry and construct the mesh prior to the analysis.

To help promote best practice in the use of computational fluid dynamics (CFD) during the design phase, Flomerics has joined the NAFEMS CFD Working Group.

Founded in 1995, the group provides guidance and information for the safe and reliable use of CFD within the engineering community.

"Flomerics has been a member of NAFEMS for a number of years, and I am sure that their experience and knowledge will be beneficial to the CFD Working Group and the NAFEMS community in general", says David Quinn, Head of Marketing and Communications at NAFEMS.

"Getting involved in the group demonstrates Flomerics commitment to the technology and the theory behind it, and that can only be a good thing for the industry".

Computational fluid dynamics was once the preserve of academics and specialists within large organisations.

Despite the dramatic increase in computing power and improved ease-of-use in recent years, only about 3% of the million-plus mechanical design engineers worldwide are currently using CFD.

One reason CFD finds limited use in product design is the effort required to clean up CAD geometry and construct the mesh prior to the analysis - something that has to be repeated every time the design is changed.

Flomerics' Engineering Fluid Dynamics (EFD) is a new breed of CFD software.

EFD is based on the same mathematical foundation as traditional CFD software, but Flomerics' unique CAD-to-CFD technology allows EFD to detect and mesh fluid regions (empty spaces) automatically, so the CAD geometry is used as is.

Unlike traditional CFD, EFD is embedded in the user's CAD system, so mechanical engineers can simulate fluid flow and heat transfer without leaving their familiar MCAD software environment.

With SolidWorks now supplying Flomerics' FloXpress to all SolidWorks 2008 customers, tools like EFD are poised to make CFD far more widely accessible.

Flomerics hopes its extensive experience in offering robust analysis tools for engineers will enable the CFD Working Group to show how CAD-embedded CFD can be used safely and reliably by practicing mechanical designers.

"EFD makes CFD accessible to a far wider audience and across all industry sectors, including education", comments John Parry, Research Manager for Flomerics.

"Through our involvement with the CFD Working Group we aim to show practicing mechanical designers how CAD-embedded CFD can be used safely and reliably to bring considerable time and cost savings during product design".
