O2P2 is an object oriented framework for the Positional Finite Element Method applied to Thermomechanical Problems. It was developed for non-linear coupled thermo-mechanical analyzes (:construction: We'll get there, eventually :construction:).
Whether it was used in whole or parts, citation is a must! Our software is under development, and a proper presentation paper is underway.
Our software is in Zenodo - thus, we got a DOI: doi.org/10.5281/zenodo.7102198

Clone the source code
git clone --recursive https://github.com/GEMeCo/O2P2.git -
This will install development dependencies and resources. Nevertheless, check above for missing resources.
-
We provided the .vsxproj file. Some configuration may be needed. Good luck 😇.

PhD obtained in 2009 from The University of Sao Paulo (USP) at Sao Carlos School of Engineering (EESC).
Joined the Federal University of Technology - Paraná (Brazil) as Assistant Professor in 2010.
Joined the University of Sao Paulo at Sao Carlos School of Engineering, in the Structural Engineering Department in 2015.
Associate Professor since 2020. Has worked on several research projects dealing with static and dynamic behaviour of composite structures using an alternative version of the Finite Element Method, based on Positions.
