OpenPhase Software

OpenPhase Studio is a powerful microstructure simulation suite made for metallic materials, ceramics and minerals. Using multi-physics models embedded in the phase-field method, materials processes such as solidification, heat treatment, mechanical testing and many more can be simulated. OpenPhase is available in two flavours, OpenPhase Studio and OpenPhase Core. OpenPhase Studio is our full-featured microstructure simulation suite with user-friendly GUI, intuitive simulation setup and on-the-fly data analysis. An open-source C++ library is available with OpenPhase Core, which includes the core OpenPhase functionality and offers full flexibility in building custom simulations.

OpenPhase enables you to:

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

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 is state-of-the-art in simulating microstructure evolution.


Intuitive graphical user-interface

Guided creation of simulations, integrated documentation and presets for various materials and processes.


Modular library

OpenPhase Studio and OpenPhase Core use a modular structure that allows combining different physical modules into a single simulation or simulate a complex process through consecutive simulation steps.


Powerful diffusion module

Realistic simulation of diffusion and phase transformation. Coupling to Thermo-Calc and Open Calphad enables realistic simulation of complex material systems.


Extensive mechanics module

Finite strain elasticity snd crystal plasticity for complex mechanics simulations of evolving or static microstructures.


Straightforward flow solver

Fluid-flow solver using Lattice Boltzmann method for calculating melt flow during solidification.


Flexible nucleation and microstructure creation

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