This application is a Python-based tool designed to read and process UCN files generated from heat transport simulations. It enables users to identify and manage hot and cold wells for thermal energy injection and production, designate observation wells, and select specific layers for detailed analysis. The app offers integrated visualization features to plot temperature changes over time, supports dynamic simulation playback through an animation sub-module, and calculates thermal recovery efficiency for selected wells. It also provides options to export processed data for further use. This tool streamlines the interpretation and evaluation of HT-ATES simulation results by offering an interactive, user-friendly interface.
