CFD Benchmark Suite v1.0

CFD Benchmark Suite v1.0

A standard, open set of cardiovascular CFD cases for testing and comparing CFD frameworks on the
same data across platforms and institutions: five patient models from the Vascular Model
Repository (AAA, two Fontan, two aortas), a derived aorta and aortoiliac case, idealized AAA and
Fontan, a tet and a hex pipe, and the 1 M-tet pipe of svMultiPhysics issue #750. 39 case levels
from about 1 M to 5.8 M linear elements (tet4; hex8 for pipe_hex), with boundary conditions,
fluid properties and units fixed for every case.

Assets

One zip per case (<case>.zip, 17 to 373 MB), each holding every level of that case:

• cases/<case>/<level>/mesh/: svMultiPhysics mesh-complete (volume VTU and face VTPs)
• cases/<case>/<level>/mfem/<case>_<level>.msh: Gmsh 2.2 binary, read directly by MFEM
• the case files and the licence notices that apply to that case
• SHA256SUMS: checksums of the 12 zips

Unzip into a checkout of the repository, or let the downloader extract only what you need:

python tools/fetch_meshes.py --list
python tools/fetch_meshes.py 0031_H_ABAO_AAA/fine --solver mfem

Every level passes tools/verify_case.py (mesh and face consistency, quality gate, volume, BCs,
0D pressure, MFEM load and smoke solve). MFEM ASCII .mesh files are not shipped; the .msh is
the identical mesh, and tools/msh_to_mfem.py writes a .mesh on request.
