AB: In response to requests from the long timescale tectonics community, we have developed Gale, a parallel 2D and 3D finite element code. Gale's focus is on orogenesis, rifting, and subduction, although it is flexible enough to be applied to such diverse problems as coronae formation on Venus and 3D evolution of crustal fault systems. Gale solves the Stokes and heat transport equations with a large selection of viscous and plastic rheologies. Material properties are tracked using particles, allowing Gale to accurately track interfaces and simulate large deformations. In addition, Gale has a true free surface and a simple programming interface that allows you to plug in your own surface process model. Gale supports a wide variety of boundary conditions, including inflow/outflow, fixed, stress, and static and dynamic friction. Gale has been extensively tested and validated and is exhaustively documented with a 100+ page manual. Gale has been run on everything from laptops to 1000+ processor clusters. Source and prebuilt binaries are freely available at the CIG website. We will discuss Gale's capabilities, present benchmark results, and demonstrate solutions to realistic problems.
