If you use OOFEM, and especially if you use it to accomplish real work, I would like very much to hear from you. A short letter or email describing how you use OOFEM will mean a lot to me. The more people I know are using this program, the more easily I can justify spending time on improvements that I hope will benefit you.

When referencing OOFEM in a publication, please cite at least one of the following papers:

• B. Patzák and Z. Bittnar. Design of object oriented finite element code. Advances in Engineering Software, 32(10-11):759–767, 2001.
• B. Patzák and D. Rypl. Object-oriented, parallel finite element framework with dynamic load balancing. Advances in Engineering Software, 47(1):35 – 50, 2012.

OOFEM releases are archived on Zenodo and have DOI, so they are directly citable:

• v2.5: <a href="https://zenodo.org/badge/latestdoi/109019710"><img src="https://zenodo.org/badge/109019710.svg" alt="DOI"></a>

In addition, you can also cite oofem web pages as

• B. Patzák, OOFEM project home page, http://www.oofem.org, 2009.
