The simulation software has practical applications in various fields, including hydrology and water environments, carbon capture, utilization and storage, groundwater contaminants, and geothermal energy exploration. Our kernel simulation module is the next generation of the HYDROGEOCAM (HGC) model, developed in 1991, and FEMWATER, developed in 1981 by Prof. Gour-Tsyh (George) Yeh. Since 2013, we have been continuously developing a fully coupled Thermal-Hydrological-Mechanical-Chemical (THMC) model at National Central University (NCU), Taiwan. However, the model is based on Fortran code, with input/output supported only in text mode. We developed the graphical user interface to reduce the end-to-end cycle time of the whole simulation process.
Significant enhancements in preprocessing tasks include geometry management in the field site. Users can set specific areas, such as boreholes or monitor well locations in two-dimension, to obtain more detail through better mesh resolution. Furthermore, users can set simplified construction parameters (e.g., layer distribution, layer split resolution in the Z direction, material information, etc.) to generate three-dimensional meshes easily. By using finite element method approaches, the versatile types of points, faces, or volumes for all the boundary and initial conditions of simulation model spatial inputs can be set by mouse clicks in our integrated user interface. This will allow researchers to use and analyze complex systems more efficiently. These enhancements collectively contribute to more streamlined, user-friendly, and powerful simulation capabilities, which can significantly advance research in various fields.
