Hi I am a current user of CCM+, I am wondering what CFX and Fluent offers in terms of solver speed, meshing algorythm and user friendlyness. I use CFD in the building industry, so I am not too worried about the turbulence models used for mach > 10...

I've worked with all 3 packages, and I think that CCM+ is an interesting and good choice.

You will probably see a merging of GUI's with regards to CFX and Fluent so that the both will use CFX-Pre and CFX-Post in the future. And that is for the better when you want to know about user friendliness. CFX post is to me the most user friendly post processing tool. But stick to CCM+ if you like it. The polyhedral mesher in CCM+ is good and the solver robustness is increasing, even though it is not yet as robust as CFX.

But keep an eye on errors on bugs in ccm+. There should be more bugs in that program compared to the others.

I expect Solver speed and parallel scalability would be better in CFX than CCM+, since it's a real CFX strength, but I don't have any benchmarks to confirm this. Anybody else compared speed between these two?
