Modeling Thermo-Hydro-Mechanical-Chemical (THMC) processes in underground formations is vital for applications such as CO2 storage, geothermal energy, contamination remediation, and nuclear waste disposal. These processes involve complex interactions among rock mechanics, fluid dynamics, heat transfer, and geochemical reactions, requiring interdisciplinary expertise and advanced computational methods.
To simplify THMC simulations, our research introduces an innovative module. This module enhances accessibility, reducing the learning curve for users. Built on the foundational HYDROGEOCHEM (HGC) and FEMWATER models by Prof. Gour-Tsyh (George) Yeh, widely used by organizations like USEPA, IAEA, USNRC, and USACE, it is also integrated into the Groundwater Modeling System (GMS).
The new module unifies pre-processing, simulation execution, and post-processing within a seamless interface. And first apply on groundwater contamination remediation. Key features include: Scenario-based templates with predefined parameters. 3D interactive visualization for conceptual modeling. Automated mesh generation to streamline simulations. Predefined 2D/3D post-processing for intuitive data interpretation. By integrating advanced visualization techniques, this module enhances THMC modeling efficiency, improving our ability to analyze subsurface phenomena. It bridges the gap between theoretical complexity and practical application, facilitating broader adoption in environmental and energy-related fields.
