[Beowulf] Building OpenFOAM

[John Hearns]

Prentice,
You have it.  And add in dependiencies on specific versions of GCC - which you have to compile up from scratch! (OK, this was in previous versions).

Hopefully I am allowed a little commercial break here. There is a company in the UK which provides experise and a supported build of OpenFOAM
http://www.totalsimulation.co.uk/wp/
A former colleague of mine in the automotive industry uses their build - as an aero engineer he wants to get on with his work, nto take the time to learn how to compile and update OpenFOAM.

(I add that there is no personal gain for me in referring to Totalsim)

I've heard about how difficult building OpenFOAM was for years. I don't think it's all that difficult, it just takes a LOT of time to build,  so when errors are encountered, the iteration time between multiple. The real difficulty arises from how poorly documented the build process is.
It's like a single page. And since it uses it's own shell scripts to manage the build process, instead of using GNU Autoconf tools, I've had to figure out how it works, and spend days digging though shell scripts to figure out the proper place to add include and lib directories.
