THMC(Thermal-Hydrology-Geo-Mechanics-Chemical), developed by the internationally renowned hydrologist Prof. Gour-Tsyh Yeh, is an advanced physical-based FEM model for simulating fully coupled processes in saturated and unsaturated subsurface environment. Designed to address a broad spectrum of water-related issues, THMC offers unparalleled capabilities in carbon sequestration, geothermal energy, nuclear waste disposal, groundwater resource management and groundwater remediation.
Recent advancements in THMC model emphasize enhanced simulation accuracy and computational stability, consolidating its standing as a leading solution in international subsurface software market. Furthermore, CAMRDA from National Central University, Taiwan, has improved the model’s accessibility and usability by designing a Windows-based, user-friendly interface platform. The platform supports fully 3D operations, enabling seamless simulation workflows with interactive visualization tools and intuitive model-building features. Its self-developed 2D/3D mesh generation engine allows users to construct detailed conceptual models and simulation-ready meshes efficiently.
To overcome the domain knowledge barrier, the software integrates a comprehensive database of frequently used parameters, including material coefficients and chemical equations, simplifying setup processes and shortening the learning curve for new users. With these enhancements, THMC has become a competitive and versatile tool for researchers and practitioners tackling complex environmental and engineering challenges.
In this study, we consider the Henry's saltwater intrusion problem as a case example to perform a simulation using THMC software. The simulation results closely align with those from the previous study (Cheng et al., 1998), serving as a reliable benchmark in the issue of saltwater intrusion. With the THMC platform, users can proficiently execute modelling and interpret the results of simulation, providing a scientific basis for decision-making analysis.
