“…A well shaped tetrahedron has aspect ratio defined as 1.00 (Si, 2013), but a bounded aspect ratio at most five also was discussed in detail by Ruppert (1995). Therefore, to ensure accurate results, a well shaped tetrahedron has a low aspect ratio (Gerritsen et al, 2015;Cheng, 2006). Considering these values and each mesh explored here, histograms are shown for both the raw and highly refined meshes: "C-type" magnet ( Fig.…”
