Dana's Commercial Vehicles Systems Division (CVSD) provides heavy truck components to OEMs in tune with the company's "under-the-chassis and under-the-hood" focus.
Interoperability Problems
"Designers create components with a number of objectives in mind, such as manufacturability, packaging, casting drafts and clearances. Sometimes these objectives interfere with the needs of a finite element analyst, i.e., a simple model that can be easily meshed. Defeaturing the models solved our problems to a certain extent, but cost us heavily in terms of FEA accuracy," explained Dr. Mangalaramanan Lead CAE Specialist.
"We needed to mesh complex components without spending too much time simplifying, while retaining as much of the original geometry as possible in order to improve the accuracy of our analysis," says Dr. Mangalaramanan.
CADfix®
"CADfix offers us exactly what we were looking for. The defeaturing functionality removes complex details included by the designers but insignificant from an engineering perspective," said Dr. Mangalaramanan. "We can run FEA with reassurance that the results will be accurate. Geometry took weeks to mesh now require only days, and the package is very simple to use, yet powerful."
"For the first time I have seen a sales person delivering me more than he could convey in words. I have used almost every feature of CADfix and it is now an indispensable part of our engineering process."
