Hi all I'm still a relative newb to Open Foam, so this might be a silly question but if I don't ask I will never learn.

I am running a simple Benchmark Flow over a cylinder using an example form
Benchmark Computations of Laminar Flow Around a Cylinder; M. Sch ̈fera and S. Turekb

On open Foam 1.7 in CAElinux 2010

The flow involves a parabolic inflow condition, so I decided to try groovyBC
however I do not have the libraries
I followed a link to the Wiki

http://openfoamwiki.net/index.php/Contrib_groovyBC

I have confirmed that i have bison
however the download links at the botom of the page apear in HTML form,
so It look like I will have to copy and paste the text of each individual file into a new text document.

am I missing an obvious trick here, is there not a .tar folder or something I could download directly?

I have managed to get the parabolic inlet profile working,

Although I only ran it over a small time period the drag and lift coefficients agree well with the benchmark solution.

Unfortunately paraFoam seems to crash every time I try to load velocity and pressure values.

I have attached a copy of the system for anyone that is interested.

Have a look at

http://openfoamwiki.net/index.php/Co...to_controlDict

The interesting part starts after "If you are experiencing problems with paraFoam"

Hi gschaider

Yes it does. If you use such stuff: COPY PASTE IT. That way the capital letters are right and you're not wasting my time. And if you had actually looked at the error message from paraview ("could not load libOpenFoam.so: cannot open shared object file: No such file or directory") or posted it here it would have been a matter of minutes (apart from having to guess your OF-version and the paraview-version)

Thanks gschaider, I guess my typing gets sloppy towards the end of a long day.
