As a CFX user it is really frustrating, especially when you're not doing much turbomachinery analysis... Is there still something, a good thing that is exclusive to CFX except the turbo machinery friendly part? because even if that's the case, I have the feeling it won't last.
Any thoughts ?
I know exactly what you mean, and I feel the same way sitting through the ANSYS "Fluid Dynamics Update" Webinars, it seems all they talk about is FLUENT, and CFX hardly gets mentioned.
I also heard of the Unified code about a year ago, and was kind of expecting it for the 15.0 release, but nothing yet.

From what I heard a couple of years ago, a preview/first version should have been released with R15, but as we know, it wasn't.

R16, maybe? It will still be (kind of) within your 5 year range, Glenn.

Many years ago I heard v14 would have a unified solver, then it became v15, then v16, and so on... apparently a working name was (is?) FLUX (FLUent+cfX)

But I wonder if we will ever see it.

Got an e-mail from an ANSYS representative today. He's saying that a beta of a CFX/FLUENT unified code MIGHT BE available with the release of 16.0...They have to keep the dream alive right?!

I've heard that ANSYS is working on unified CFD code now, but it won't appear even in 16 release. Also I heard that head of CFD line is fluent-guy, therefore fluent gets more attention.

I'd also like to see Ansys Meshing and ICEM merge.

I'd love the ease of use of Meshing, combined with the power of ICEM.

I know you can do something similar by going into meshing, create a new method and select "External ICEM solver" or something along those lines. However in my experience it's quite buggy. I want one unified meshing program.

I think that one of the differences are chemical reactions (combustion, etc.) which can be solved in the FLUENT solver.

CFX can model chemical reactions. I have not done a detailed comparison of reactions both of them can solve, but I suspect they can both handle most reactions you are likely to come across.
