This data set contains the simulation data for the results presented in [S. Burbulla, M. Hörl, and C. Rohde (2022). "Flow in Porous Media with Fractures of Varying Aperture." Submitted for publication, https://doi.org/10.48550/arXiv.2207.09301].

We consider the numerical solutions of single-phase fluid flow governed by Darcy's law in a fractured porous medium for four different scenarios. For each scenario, we provide the raw vtk-files (.vtu and .vtp) of the pressure field for different values of the fracture aperture and for discontinuous Galerkin discretizations of four different discrete fracture models and one full-dimensional reference model. These files can be reproduced by running the script main_comparison.py of the corresponding source code (see [S. Burbulla, M. Hörl, C. Rohde (2022). "Source Code for: Flow in Porous Media with Fractures of Varying Aperture", https://doi.org/10.18419/darus-3012, DaRUS.]). Moreover, we provide visualizations (*.pdf) of the simulation results for each scenario that can be reproduced by running the script plot_comparison.py which is part of the corresponding source code. This includes, for each value of the fracture aperture, a visualization of the full-dimensional reference pressure and velocity, as well as a plot of the effective fracture pressure and the corresponding absolute error (compared to the full-dimensional reference solution) for the different discrete models. In addition, the L2-error of the effective fracture pressure is plotted as function of the fracture aperture for the different reduced models.

Scenario 1a (section-6.1.1.tar.gz): Flow perpendicular to a sinusoidal fracture with constant total aperture (two-dimensional).
Scenario 1b (section-6.1.2.tar.gz): Flow perpendicular to a sinusoidal fracture with constant total aperture (three-dimensional).
Scenario 2 (section-6.2.tar.gz): Flow perpendicular to an axisymmetric sinusoidal fracture (two-dimensional).
Scenario 3 (section-6.3.tar.gz): Tangential flow through an axisymmetric sinusoidal fracture (two-dimensional).

A detailed description of the different scenarios can be found in Section 6 in [S. Burbulla, M. Hörl, and C. Rohde (2022). "Flow in Porous Media with Fractures of Varying Aperture." Submitted for publication, https://doi.org/10.48550/arXiv.2207.09301].
