Important

This is the new repository for OpenDiHu! Here you will find OpenDiHu's latest version.

The original repository of OpenDiHu is no longer mainained. There you can find versions 1.0, 1.1, 1.2, 1.3 and 1.4 of OpenDiHu.

Overview

OpenDiHu is a software framework to solve 1D, 2D, and 3D multi-physics problems in parallel with the Finite Element Method. It is used in the domain of skeletal muscle simulations: Electrophysiology, contraction, neuro-chemo-electro-mechanics. Design goals are usability, performance and extensibility.

The software is developed at SGS and IANS at the University of Stuttgart.
