title: Large eddy simulation of blood flow in a realistic model of the Circle of Willis

description: The dataset was produced using fully resolved Large Eddy Simulation (LES) and multiharmonic rheological flow models in a realistic <em>in silico </em>phantom of the CoW. Researchers and biomedical engineers could utilize this dataset to fine-tune their CFD models and establish standard reference simulation(s) before carrying out further parametric studies. Having the dataset released under an open-access license encourages the community to further expand the dataset using different investigation modalities. <br> CoW Model reference: N. Wilson, K.
