Case 3 - Small Features: Benchmark Data for Single-Phase Flow in 3D Fractured Porous Media

Results from the benchmark case 1 for verifying single-phase flow simulations in three-dimensional fractured porous media, as described in a 2018 arXiv publication. The dataset contains simulation results from an MPFA scheme in the Dumux simulator and a reference solution from a finer mesh, organized into sub-folders with VTK format files for pressure and tracer concentration over time. It was contributed by Dennis Gläser from the University of Stuttgart.

Use Cases

• Verifying numerical solvers for porous media flow based on the provided pressure and tracer concentration solutions.
• Benchmarking mesh refinement strategies using the three available refinement levels indicated in the filenames.
• Analyzing tracer concentration evolution over time using the provided 'dataovertime_*' files.
• Comparing simulation results against a high-fidelity reference solution from a finer mesh.

Strengths

• Includes a reference solution from a simulation on a finer mesh, providing a benchmark for accuracy.
• Results are available in standard VTK format, compatible with open-source visualization software like ParaView.
• Contains results for three different mesh refinements, allowing for convergence studies.
• Source code for reproducing the results is publicly available, supporting reproducibility.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
