Accelerate Automotive Design with FloEFD 2

A new class of Computational Fluid Dynamics (CFD) analysis software, ‘Concurrent CFD’, is proving to be highly effective at performing heat, fluid and airflow analyses, enabling Engineers to accelerate key decisions at their workstations and without the need for CFD specialists. This intuitive MCAD embedded process allows designers to optimize a product during the design stages reducing manufacturing costs across a wide range of automotive parts and systems such as heating, cooling, fuel delivery systems, braking systems, exhaust systems, body panels etc, etc.
Traditional and up-front CFD approaches have either been difficult, cumbersome or time consuming in their use, but with Concurrent CFD, mechanical design teams can accelerate the design process, increase their productivity workflow, reduce re-spins and increase profits. This paper includes two case studies using Mentor Graphics

It’s now common knowledge that computer modeling/virtual prototyping in the form of Computational Fluid Dynamics (CFD) can make major contributions in reducing product costs and accelerating time to market. However, many managers fail to realize
that the latest software advances are now making these benefits both accessible and affordable to small- and mid-sized enterprises. This is in part thanks to a new design/analysis technology known as ‘Concurrent CFD’, created by leading
simulation software company Mentor Graphics. Aimed specifically at the mechanical design engineer, Mentor Graphics have introduced FloEFD, a Concurrent CFD software that is embedded– concurrent, in a users MCAD system. With it there is no longer the need to hire or train CFD specialists, outsource analysis to consultants, or conduct tests on expensive multiple physical prototypes; instead, a design engineer - with standard training and working in any size company,can use their existing knowledge to successfully perform flow and heat transfer analyses all within their already familiar MCAD environment, helping increase workflow and dramatically reducing the
number of physical prototypes needed.
This breakthrough arose because FloEFD is able to simplify the process of setting up and running a flow or heat transfer analysis. Certainly, there will always be a few very demanding applications where a more advanced CFD knowledge is needed to fine-tune the meshing and solver settings in order to converge to a solution. However, experience shows that using their existing knowledge, design engineers with no specific training in CFD codes can correctly perform an analysis in
roughly 80% to 90% of the situations they encounter. This ability to take CFD out of the exclusive domain of specialists and bring it into the mainstream represents a fundamental change in the design process. Just as the shift from 2D to 3D CAD required a mental leap, so does FloEFD –and the results are perhaps even more significant.
