openCFS

openCFS (Coupled Field Simulation) is a finite element-based multi-physics modelling and simulation tool. With about 20 years of research driven development, the core of openCFS is used in scientific research and industrial application. The modelling strategy focuses on physical fields and their respective couplings.

free and open source

under the MIT license, openCFS can be used by anyone, even commercially (as long as you include the original copyright and license notice in any copy of the software/source). You can check out the source code or download the latest release for Linux or Windows.

state of the art features

range from capabilities for various physical fields and their couplings, non conforming grid techniques, and structural optimization, to flexible data exchange with third party software, scriptable XML input, and powerful built-in third party libraries.

quick to learn

with an extensive set of examples from our user documentation and an extensive testsuite. Furthermore openCFS is used in several university courses, and learning material is freely available.

active community

organised in an association devoted to the promotion of the software. Members range from university researchers at TU Wien, FAU, TU Graz over individuals and students to companies applying openCFS to industrial problems.

commercial support

for openCFS is available through the company EnSimTech UG which was founded in 2020. EnSimTech allows commercial users of openCFS to benefit from commercial support, integration and adaptions of openCFS to fit the commercial customer needs.

Association

Association for the promotion of the software

Verein zur Förderung der Software openCFS

The association "Verein zur Förderung der Software openCFS" has been founded in 2020 and its main goal is the promotion of the open source software openCFS. The main objectives of the association are

Comprehensive maintenance and further development of the open source software openCFS
Promotion of the use of openCFS for scientific problems which are solved with the help of numerical simulation, thus leading to new, innovative products for the benefit of mankind (Technology for People)
Promotion of the scientific documentation of openCFS and the use of openCFS in higher education
Promotion of young scientists, especially students at universities in Austria and Germany and worldwide, in the field of numerical simulation of complex technical systems

User prize presentation

Once a year a user prize is awarded within the framework of a user meeting.

Developer prize presentation

Once a year a developer prize is awarded within the framework of a user meeting.
