Are any of you using CAD-free CFD? I have read a lot of paper about it. The idea is to place CFD upstream of the CAD in the design process. The CFD engineer provide to his CAD colleagues dimension range (length, diameters, thickness, etc...) and limits within which he can design the product according to the CFD analysis. And then the final design comes back to cfd to check it is within the ranges and results. It is reported to decrease the time to market much more than "integrated CFD in the CAD" where endless discussion occurs. This allows for a margin for errors and assumptions from the CFD side. The knowledge of these margin and errors comes from experience or expertise only. It is a more realistic approach in the manufacturing world.
What is your view on this?
