GeoPS ([http://www.geops.org](http://www.geops.org)) is a program designed for this purpose in which both input and output are done through an intuitive graphical user interface. GeoPS provides a wide range of phase equilibrium calculations based on a novel Gibbs energy minimization algorithm. The algorithm provides for exceptionally robust and computationally efficient solution to the phase equilibrium problem by successive alternation between alinear programming step to identify stable phase compositions and a nonlinear programming step to refine the compositions estimated during the linear programming. Applications include calculation of various types of phase diagrams and path-dependent phase fractionation. By combining an easyto-use graphical user interface with a robust and efficient solver, GeoPS makes phase equilibrium modelling accessible to researchers and students with minimal training and provides a powerful tool for understanding natural phase relations and for planning experimental work.  \nKEYW O R DS  \nmetamorphism, phase diagram, phase equilibrium, thermodynamic modelling, visual computing  \n1 | INTRODUCTION  \nAccurate thermodynamic modelling of natural rocks is a challenging petrological task. In the past few decades, significant progress in the development of thermodynamic datasets and activity models for phases of petrological interest has been made, increasing our ability to predict complex assemblages, composition and phase relations (e.g., Berman, 1988; Helgeson et al., 1978; Holland et al., 2018; Holland & Powell, 1998, 2011; Naumov, Ryzhenko, & Khodakovsky, 1974; Powell & Holland, 1988; Stixrude & Lithgow-Bertelloni, 2011; White, Powell, Holland, et al., 2014). At present, there are numerous computer programs for calculation of equilibrium phase  \ndiagrams and/or phase diagram sections, based on different strategies. Among them, three are used widely by petrologists: THERMOCALC (Powell & Holland, 1988; Powell, Holland, & Worley, 1998), Perple_X (Connolly, 2009; Connolly & Kerrick, 1987), Theriak/Domino (de Capitani & Brown, 1987; de Capitani & Petrakakis, 2010). Each program has advantages and limits that have been summarized elsewhere (Connolly, 2017; Lanari & Duesterhoeft, 2019). However, one of their common characteristics is that they are implemented as console-based applications that are not user-friendly, especially for novice users. In this contribution, we present anew computational strategy that is implemented through an intuitive graphical user interface (GUI) named GeoPS.  \nJ Metamorph Geol. 2021;1–13.  \n[wileyonlinelibrary.com/journal/jmg](wileyonlinelibrary.com/journal/jmg)  \n© 2021 John Wiley & Sons Ltd  \n1  \nGeoPS is a visual computing platform for phase equilibrium modelling based on Gibbs energy minimization.
