<div dir="ltr">Paul,<br>Thanks for such detailed information! They are really helpful. Do you have any experience with Airpak and Flovent? Heard that these two tools are specially tailored for built environment.<br><br>Thanks again.<br>

<div dir="ltr" align="left"><font color="#0000ff" face="Arial" size="2"><span>If you want to go full on with CFD, then I'd suggest
Fluent (<a href="http://www.fluent.com/" target="_blank">http://www.fluent.com/</a>)
everyday. It is very widely used and well trusted tool. ICEM is
a good meshing tool, but we like Pointwise and Gridgen for it's meshing
simplicity.</span></font></div>

<div dir="ltr" align="left"><font color="#0000ff" face="Arial" size="2"><span>If you want the same sort of capability and are willing
to use mainly text input then I'd suggest OpenFoam (<a href="http://www.openfoam.org" target="_blank">http://www.openfoam.org</a>) - a very
powerful open source CFD tool. You could use something like pointwise to
mesh it, output a fluent case file and then openfoam has it's own fluent case
file converter program which you could use to then convert it and process
it. You'd probably need a decent post processor too, but clearly then you
are only paying for those programs as openfoam itself is free. If
you can do it all by text then you wouldn't need to pay anything at all.
It will require you to use Linux though. I saw a pre-compiled bootable
live CD distro of this recently which was quite impressive so it allows you to
check it out just by inserting CD into computer and booting to it. The
link for that is: <a href="http://www.caelinux.com/CMS/" target="_blank">http://www.caelinux.com/CMS/</a></span></font></div>

<div dir="ltr" align="left"><font color="#0000ff" face="Arial" size="2"><span>Of the cheaper and possibly more usable programs for
quick built environment analysis. Cham Pheonics (<a href="http://www.cham.co.uk/" target="_blank">http://www.cham.co.uk/</a>) is good value
for money. It's Flair add on is pretty simple to use. I'd still
personally get a good CAD program to make sure your geometry is spot on before
importing it, but then it would do the job well. A lot of companies use it
becasue of it's relative simplicity and good price.</span></font></div>

<div dir="ltr" align="left"><font color="#0000ff" face="Arial" size="2"><span>Another which is aimed at non-CFD experts is
DesignBuilder CFD (<a href="http://www.designbuilder.co.uk/" target="_blank">http://www.designbuilder.co.uk/</a>).
It is in beta test stage and looks promising. It'll be great for simple
stuff. Wouln't recommend anything that uses just cartesian grids for
complex jobs, but for the large majority of jobs it will suit, especially if
it's internal room flows, etc. Should be quite competitive on the price
too.</span></font></div>

eaiser to use?</div>
