open Delft Advanced Research Terra Simulator (open-DARTS)

Abstract

Open Delft Advanced Research Terra Simulator (Voskov et al., 2023) is a simulation framework for forward and inverse modelling and uncertainty quantification of multi-physics processes in geo-engineering applications such as geothermal, CO2 sequestration, water pumping, and hydrogen storage. To efficiently achieve high levels of accuracy on complex geometries, it utilizes advanced numerical methods such as fully implicit thermo-hydro-mechanical-chemical (THMC) formulation, a highly flexible finite-volume spatial approximation and operator-based linearization for nonlinear terms. open-DARTS goals are computational efficiency, extensibility, and simplicity of use. For this reason, open-DARTS is based on a hybrid design with an efficient core C++ implementation wrapped around a highly customizable and easy-to-use Python code.
