There are seems three related software of Simulation CFD, there are Autodesk Simulation CFD, Autodesk Simulation CFD Advanced, Autodesk Simulation CFD Motion. It seems I never find the other software except Autodesk Simulation CFD, Can Someone tell me the reason ?
I am guessing that you are looking for the installation media for the various Simulation CFD products. As far as I know, there is only one installer for Simulation CFD, but your product key and license unlocks the different tiers of your solver (advanced, motion).
I think Normal, Advanced and Motion modules are part of same software, with increasing capabilities. Depending on your requirements of physics, you'd pay the licence fee.
That is correct. There is only 1 installer that includes everything. Depending on your licesnse you will get access to different levels (basic, advanced, and motion) of the solver.
Just make sure you get either the 32 bit or 64 bit installers.
