Abstract: This note aims to introduce and share with a broader community a collection of sixteen anatomically and numerically accurate high-resolution, 2-manifold CAD compatible head models intended for electromagnetic simulation (neuromodulation and neuroimaging) tasks. Our experience has shown that these models may be quite useful when testing software performance and convergence in realistic anatomical scenarios or performing side-by-side software comparisons. The collection is based on MRI data from the Human Connectome Project (HCP) segmented using the SimNIBS processing pipeline. The average number of triangular surface facets in a model is 866,000, the average triangle quality is 0.25, the average edge length is 1.48 mm, and the average surface mesh density or resolution is 0.57 points per mm 2 . This mesh resolution corresponds approximately to the resolution of the high-quality 3 T images. Each model contains skin, skull, CSF (cerebrospinal fluid), GM (gray matter), cerebellum, WM (white matter), and ventricles 2-manifold compartments. The companion mesh processing tools within the MATLAB platform include evaluating cross-section model topology, shell deformations, and model refinement (oversampling). The models are fully compatible with ANSYS Electronics Desktop, SimNIBS, CST Studio Suite, Sim4Life/SEMCAD, and other electromagnetic software packages.
