Although many people join the our community every year, a few groups and individuals around the world have been using Nek5000 consistently and contributed to our project for a very long time.

If you want to take an active hand in making Nek5000 even better, there are many ways you can contribute – adding new physics, improving our documentation, creating tutorials etc.
