VaMPy
What VaMPy is
VaMPy is a free Python package of automated scripts for preparing, running, and analyzing vascular morphologies. Its preprocessing workflow creates volumetric meshes, applies physiological boundary conditions, and places probes for velocity and pressure sampling. Meshing supports Laplace, Taubin, and Voronoi smoothing, flow extensions, boundary layers, regional refinement, and constant, diameter, or curvature methods. Documentation includes Oasis and OasisMove computational fluid dynamics cases for the internal carotid artery and left atrium, including a moving-domain atrium example. Simulations can run in parallel with MPI commands. Analysis scripts calculate wall-shear-stress, turbulence, and geometric measures, including oscillatory shear index, relative residence time, and endothelial cell activation potential. XDMF and HDF5 results can be viewed in ParaView, while vampy-probe plots probe data with Matplotlib. Local preprocessing and HPC execution over SSH are documented. Conda and Docker installation options are provided.
