A CFD engineer makes proposals for a significantly better performing design and gets turned down by the CAD engineer (he typically has never met before) because his insights came too late or are not manufacturable at all. In some twist of this genre, the CAD designer has a great solution that fulfills all packaging constraints and he would have loved to understand the flow behavior but he has no tool to do so.

In engineering, CAE simulation plays an increasingly powerful role in product design. But the factor limiting its more explosive growth is the reliance in many of the disciplines on experts and analysts. There is certainly a desire to be able to democratize at least a subset of the CAE simulation areas and broaden the pool of engineers that can effectively conduct these analyses and benefit from the more immediate performance feedback of their designs.

The traditional CFD process hasn't changed in 30 years, and the bulk of CFD done today (as much as 80% we estimate) complies with this accepted norm of creating a geometry in CAD, exporting it to a meshing tool, meshing it, setting up and running a CFD solver, post-processing results, going back into the geometry, altering it and continuing to do these design loops again and again.

CFD simulates the flow of liquids and gases by performing millions of numerical calculations. CFD analysis is typically carried out earlier in the design process even before the first prototype is made. With high-speed supercomputers, better designs can be achieved quicker, faster, and cheaper. Multiphysics is advanced CFD involving multiple physics coupled to mimic the real behavior as accurately as possible.
