The GEO++ code

GEO++ is a code for simulation of the flow in networks of fractures. The software is written in C++ and can be executed in parallel on distributed memory machines. The key features of GEO++ are:

Robustness to geometrcal complexities
Reliability, with automated and rigorous error prediction and control routines
Efficiency, with high parallel scalability
Applicability to randomly generated networks for Uncertainty Quantifcation and Machine Learning applications
Modularity and flexibility

Further details on the GEO++ software are described in this presentation

Scalability results of GEO++ — Parallel scalability of GEO++ for three different fracture networks using up to 128 processes

Mesh adaptivity — Example of adapted mesh, automatically refined only near traces with higher fluxes
