FEAPB (Finite Element Analysis of Piezoelectric Beams) is a software for solving linear static, modal and dynamic three-dimensional piezoelectric beam problems. FEAPB is the outcome of a European Erasmus Mundus project on "Higher Order Finite Elements for Piezoelectric Energy Harvesting Beams" (find the theory in the directory "Theory_Behind_FEAPB"), carried out at the Civil & Computational Engineering Centre in Swansea University, UK.


FEAPB has been specifically designed to be used as a GUI-based application and not as a front-end API, and solely for educational purposes. Although, pull requests, issues and bug reports are always welcome, the source code is distributed just for convenience as part of the open-source license.

FEAPB has been developed in full compliance with ISO C++11 and the use of following open-source graphical/numerical linear algebra libraries is highly appreciated:

Eigen 3.2.0	MPL2
Qt 5.1.0		LGPL
Boost 1.5.4		Boost (BSL)          
QCustomPlot 1.0.1	GPL

The user-interface (FEAPB.exe) has been successfully tested on Windows 7, Windows 8 and Windows 8.1. The run-time libraries provided are for MS Windows.
