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.

OpenDiHu has moved!

Important

OpenDiHu has moved to its own GitHub Organization where it continues to be actively maintained and developed as OpenDiHu version 2.x.

• Go to the new opendihu repo
• Read the new documentation page

You are on the repo of the previous codebase as of 01/2024, containing the stable OpenDiHu version 1.4 and the Documentation for version 1.4.

Installation

Refer to the documentation for detailed installation instructions.

However, if you usually skip instructions, do the following:

git clone https://github.com/maierbn/opendihu.git && cd opendihu && make

If there are error messages, have a look at the log file config.log.
