Abstract
EIT-MESHER (<a href="https://github.com/EIT-team/Mesher" target="_blank">https://github.com/EIT-team/Mesher</a>) 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). <strong>Funding statement:</strong> This work was supported by an ARCHER eCSE grant (eCSE13-11). James Avery was supported by the NIHR Imperial BRC.
Highlights
The Electrical Impedance Tomography (EIT)-MESHER is a C++ based open source software which generates stable, good quality meshes (Figure 1) for solving the EIT forward solution
The software is based on the CGAL geometry processing kernel and utilises the extended Delaunay triangulation over binary domains in combination with a number of flexible post-triangulation optimisers [1]
The travis.yml script runs a series of examples, using data in examples/, which are fully documented in the examples/ folder with sample input and output data
