The Vascular Model Repository

What it is

The Vascular Model Repository, a sister project of SimVascular, is a library of computational models of normal and diseased human cardiovascular and pulmonary anatomy and input and output boundary conditions for various physiologic states. Most models in the repository were created with SimVascular.

Its purpose

These models can be used to simulate cardiovascular and pulmonary solid and fluid mechanics and will provide spatially and temporally-resolved benchmark solutions that can be used by academic, government and industry researchers to verify their computational methods. The SimVascular project provides an open source package for simulation to accompany the data provided in the model repository.

Supercomputing Gateway

The SimVascular Supercomputing Gateway provides access to High-Performance Computing (HPC) clusters for running simulations using SimVascular CFD solvers. Simulations benefit from the performance levels that only large-scale HPC systems can offer and typically run an order of magnitude faster than on most workstations.
