EIT-MESHER – Segmented FEM Mesh Generation and Refinement

Abstract

EIT-MESHER (https://github.com/EIT-team/Mesher) is C++ software, based on the CGAL library, which generates high quality Finite Element Model tetrahedral meshes from binary masks of 3D volume segmentations. Originally developed for biomedical applications in Electrical Impedance Tomography (EIT) to address the need for custom, non-linear refinement in certain areas (e.g. around electrodes), EIT-MESHER can also be used in other fields where custom FEM refinement is required, such as Diffuse Optical Tomography (DOT). Funding statement: This work was supported by an ARCHER eCSE grant (eCSE13-11). James Avery was supported by the NIHR Imperial BRC.
