Dealing with the consequences of ‘dirty’ or complicated CAD data has long been the biggest bottleneck in the CAE process and, until recently, was the single largest obstacle preventing the routine implementation of numerical simulation early in the industrial design process.

Although the route from CAD model to CAE solution has been much improved in recent years, with the introduction of better translators and CAD-embedded CAE simulation technology, there still exists a significant group of problems where CAD geometries are too big or complex to be handled easily.
