PROFILE
Vidar Stiernström
In December 2024, Chris Stierns developed and integrated an explicit time integration solver for rate-and-state friction into the GEOS-DEV/GEOS repository. Leveraging C++ and numerical methods, Chris implemented a Runge-Kutta 3(2) scheme with a PID-based adaptive time-stepping controller, enhancing the physics solver framework’s ability to handle complex frictional behavior. The work included updating contact field definitions to ensure compatibility with the new solver and streamline data integration. By focusing on adaptive stepping, Chris reduced the need for manual time-step tuning, resulting in more stable and reliable physics simulations. The project demonstrated depth in finite element and physics simulation techniques.

Dec 1, 2024December 2024 (GEOS repo GEOS-DEV/GEOS) focused on delivering a high-fidelity explicit time integration path for rate-and-state friction, with RK3(2) accuracy and PID-based adaptive stepping. The feature was integrated into the physics solver framework and the contact field definitions were updated to support the new solver. No major bugs were flagged as fixed this month; the emphasis was on delivering a robust solver and ensuring data-model compatibility.
