Oofem.org - Project status, challenges and needs

Paper in proceeding, 2020

The paper describes the object-oriented design of OOFEM, a general, open-source finite element solver. The design combines several design approaches, that contribute to highly modular and extensible structure and that allowed sustainable development over the last two decades. The current capabilities are briefly presented. The aim of the paper is also to discuss some challenges and needs not only for the future development of the code, but also for the open-source modelling community.
