A new add-on for the Theriak/Domino software package
- Theriak_D is a new add-on for the open source Theriak/Domino software package.
It works as an interface, providing the opportunity to process thermodynamic data in a programming environment like C, MATLAB® or SciLab©.
- The Theriak/Domino software package (written in Fortran) provides a wide range of thermodynamic equilibrium calculations and illustrations facilities (de Capitani & Petrakakis, 2010), based on the Gibbs free energy minimization (de Capitani & Brown, 1987). However the program is restricted to its own environment. To learn more about the Theriak/Domino software package and its installation, read these files Theriak/Domino User's Guide and Input and data.
The Theriak_D add-on allows the user to process thermodynamic data, calculated by Theriak/Domino, outside the package. Thus, the add-on provides the opportunity to calculate thermodynamic properties in a programming environment like MATLAB®, SCILAB© or C, calling Theriak/Domino from a script.
Theriak_D allows the user to compute chemical and physical parameters (like the solid rock density/volume/weight, the amount of free fluids or the molar amount of stable mineral phases) along any pressure-temperature path and P-T grid. For example, the solid rock density of a 2D-temperature-pressure field is calculated, portraying a simplified subduction zone.
Using Theriak_D in a similar manner opens up thermodynamics to people with only a basic knowledge of phase diagrams and similar thermodynamic illustration techniques, e.g. by illustrating thermodynamic properties in a more familiar setting like subduction zones. The tool will, hopefully, support other ideas and functions that combine thermodynamics and geodynamic models. Such combined models may improve our understanding of geodynamic processes.
This website introduces Theriak_D and includes typical examples of its functionality.

The Theriak_D add-on is still under development, any comments or suggestions to stimulate discussion and improve the content are welcome. The site content will grow gradually over time (new functions, scripts...). Do not hesitate to get back to see what's new or contact us.
Enjoy your visit!
