GEOMODELATOR reloaded – now with GUI and client-server architecture

GEOMODELATOR is a Python-based Open Source software package for translation of static geologic models into regular structured simulation grids considering element partitioning by complex model geometries (Nakaten, 2024; Nakaten and Kempka, 2023). In view of the vast legacy data available from geologic and hydrocarbon exploration, it provides a basis for site-specific assessments of geologic subsurface utilisation in terms of risk assessments, as well as operational design and optimisation.

We have further developed the GEOMODELATOR software package to fit into a modular client-server based architecture for a more robust modelling workflow, which allows to transfer heavy computational workloads to dedicated servers providing adequate resources and memory. Consequently, models with high grid element counts can be developed on low-memory client systems like laptops. Furthermore, a Graphical User Interface (GUI) has been developed to allow modellers to implement static models and directly review the results without the need for data conversion for its visualisation in third-party software packages such as Paraview (Utkarsh, 2015).

The present contribution shows the application of GEOMODELATOR to generate a numerical grid for a simulation study on fluid flow and halite transport to account for potential impacts of geologic subsurface utilisation.
