You can download a trial version of CD-Adapco software,
But I Agree for the budget point of 0 there's not much choice!

You're going to need more than 2 or 4 Gbytes memory for any real CFD
usage.
Seriously, these days people are speccing 4gigs for office workstations.
Regarding memory bandwidth, note that I said Nehalem - which are getting
good benchmark results
For CFD codes.
IF I were you I would seriously be considering my budget and looking at
a as good a Nehalem
Workstation as I can afford.
Sorry, I know this goes against the list's origins in making good use of
cheap or surplus hardware,
And I hang mu head in shame. I also hang my head in shame at using
Outlook which Capitalises Every Line.
