OpenPhase - Microstructure Simulation

OpenPhase is a powerful microstructure simulation suite made for metallic materials.

Simulation Software

OpenPhase Studio is a powerful microstructure simulation suite made for metallic materials. Using cutting edge scientific development, materials processes such as solidification, tempering, mechanical testing, etc. can be simulated. OpenPhase Studio provides well known materials data such as stress-strain diagrams and composition maps without the need for extensive experiments. Additionally, 3D data on all simulated quantities provides new insights into materials development.

  • Innovate and accelerate materials development
  • Complement experiments
  • Optimize processes through better understanding of materials behavior

Application: Solidification


The phase-field method was once developed for this very problem: casting simulations. Since then, many new developments have raised this method to the tool of choice for researching microstructure development and evolution during and after casting.


In this dendritic solidification simulation conducted with OpenPhase, the focus- lies on the transport of alloying elements by means of fluid flow and diffusion in liquid, as well as solid. Fluid flow is visualized with coloured lines, illustrating flow velocity.

Our Products


We offer our software ‘OpenPhase Studio’ as a one time purchase with 3 years of support or as an annual subscription including full support.


OpenPhase support helps you quickly find the right simulation setup for your material and process parameters.


OpenPhase training is available for beginners and advanced users and will immediately enable you to be productive with OpenPhase.

Custom Solutions

We offer custom simulations tailored to your research, implementation of new material models, parameter studies and development of custom interfaces.

Application: Virtual Creep test

In the quest for more fuel-efficient turbines, developing heat resistant materials for turbine blades is a high priority. Mechanical properties and especially creep behaviour at high temperatures are of utmost importance, as turbine blade elongation determines the effective lifespan of the blade.
OpenPhase is used here to simulate microstructure evolution under creep conditions and visualize creep behaviour, stress-strain diagrams and other properties of the simulated domain for more efficient material research.

OpenPhase Features

The development of OpenPhase started in 2008 at ICAMS, one of the world-leading materials simulation institutes. With today over 50 man-years of development, OpenPhase is the most feature-rich phase-field code available. Continuous development by the OpenPhase Solutions Team ensures that OpenPhase remains the state-of-the-art in simulating microstructure evolution.

Based on opensource OpenPhase library

The OpenPhase Library is an opensource library containing the multi-phase-field method as well as the various physics models included in OpenPhase. Advanced users can implement their own models and methods, supported by the OpenPhase Solutions team.


Opensource Software

We are living for free software. For OpenPhase Solutions GmbH, open source software is a commitment – we are working in a close collaboration with the “Interdisciplinary Centre for Advanced Material Simulation” at Ruhr-University Bochum on the development of the OpenPhase Library. The OpenPhase Library is published under the GPL v3 license.
