Hi STAR friends. We are considering buying numeca Hexpress for grid generation for car/truck external flow. It is fast and the grids are pretty good but, not many people use it. Could some one tell me if they had bad experience with it?

We had a demo for awhile. It makes pretty mesh when it works. The code has both local refinement and "extrusion layers". However, the version we had was 32bit code and somewhat inefficient with memory. If that's still the case, you will run out of cells quickly trying to build aero models.

we are using Hexpress since 1 year for internal flow applications using alpha workstations. We have generated models up to 3 millions of cells with local refinements and boundary layers extrusions.
