Why OpenPhase?

A powerful tool to simulate complex scientific problems

Smart microstructure creation

Easy creation of initial microstructures, realistic nucleation based on various properties.

Extensive physical modules

Diffusion, thermodynamics, mechanics, chemical, fluid-dynamics, magnetism, electrics, etc.

All-in-one design workflow

OpenPhase has a modular structure which allows easy extensions of the library and simplifies the development of user programs.

The Academic Version is open-source, which can be freely downloaded, modified, and shared (in modified or unmodified form) by anyone. The Academic Version is distributed under the GNU General Public License (GPLv3).
Yes, you can build a project and a complete application as you like. More modules can be easily integrated. Detailed instructions on getting started and developing your project are available in the most recent version of the documentation.
The Academic Version serves as the foundation for the Commercial Version. Additional features like an intuitively graphical user interface (GUI), an interface to commercial CALPHAD databases, and finite strain plasticity are provided in the commercial version. Support for non-professionals in the phase-field theory and its application in numerical simulations is provided in the form of customized solutions for their materials problems.
