μCT geometry, OpenFOAM solvers, case

The archive Geometry, case contains the input data and OpenFOAM case needed to reproduce the permeability results. All simulations were conducted using OpenFOAM v2406 (https://www.openfoam.com/news/main-news/openfoam-v2406) Geometry/sandstone_image.raw - 1000×1000×1000-voxel RAW volume,Geometry/sandstone_pore_surf.stl - STL surface mesh of the same volume, Geometry/cubic_subdivision - folder with cubic subdivision geometry in STL format Openfoam_case/ - complete steady-state single-phase flow case (OpenFOAM v2406) How to run the case: Navigate to the OpenFOAM case directory cd $FOAM_RUN/CaP_cells_directory/Openfoam_case Copy the STL file from a chosen geometry into constant/triSurface/, for example:cp ../Geometry/cubic_subdivision/cubic1.stl constant/triSurface/mv constant/triSurface/cubic1.stl constant/triSurface/test2.stl(The geometry file must be renamed to test2.stl — this is the expected name configured in snappyHexMeshDict) Adjust blockMeshDict according to the bounding box of the selected geometry. Optionally, adjust boundary conditions in the 0/ directory. Run the simulation using the provided script: ./run.sh DBSfoam - Darcy-Brinkman-Stokes flow solver darcyfoam - Darcy flow solver
