Sadly VisIt (https://wci.llnl.gov/codes/visit/about.html) hasn't been ported to FreeBSD so far. This completely open source package has many Linux users, and is extremely robust for scientific visualization. just wondering if there is any chance that I get it working on my box. thanks Arash P.S : I kind of went through compiling from the source but it seems to me it has so many dependencies that I stopped doing it completely. any help would be appreciated.
