With the move to git, we have decided to reorganize the sources to improve modularity.
Most of what used to be in trunk/nek now lives in core, including the all-important makenek.
We hope the rest of the directories are self describing: you can find things like nekmpi and nekb in bin or genbox and genmap in tools.
The examples have been moved into a seperate repository, nek5000_examples, to keep this one light-weight.
You can download the latest release of nek5000 as a zip or a tarball. You can also clone the repository with git:
git clone https://github.com/Nek5000/nek5000.git -b master
or even check it out with svn!
svn co https://github.com/Nek5000/nek5000.git/branches/master nek5000
nek5000 works the same way it used to: build cases with core/makenek and run them with a script, e.g. bin/nekmpi.
