need to know about BlueridgeNumerics
 
Based on my documentation The Blue Ridge Numerics is the solid works of the CFD // can somebody comment on this and give me more feedback //

It's a FEM CFD code with all attendant problems of FE: slow, requires tons of RAM and according to my documentation prone to computing nonsense (more often than you care to tolerate). It has a good CAD interface though (according to their documentation).

Nonsense Clif... It is quite RAM efficient, quick, and accurate....

what, compared to a FV approach?

What do you mean by compared to a FV approach? Have you run cfdesign benchmarking and compared it to some FV-based code?

No, just going on general experience backed up by Clif's comments. BRNI seem to be focussed on CAD integration (direct cad integration). I doubt though that the focus is at the expense of evolving the core CFD capability but when developing software you can't mature all aspects of the technology at equally expansive rates.

I meant the comparison to FV method based codes. The only exception when FE CFD codes are competitive with fV involves slow (low Re) number flows or non-Newtonian flows (which are also slow). In those case the higher order accuracy FE can provide good accuracy or coarse meshes due to the smoothness of the flow field. I believe that's how Fluent markets their FE codes, like Fidap and this makes a lot of sense. (I don't work for Fluent.)

Those are extremely overreaching statements, do you base them on your work in finite element code development?
