Description
OpenMEEG implements boundary element solutions for simulating electromagnetic fields in the quasistaticregime. Originally designed for the forward EEG and MEG problems (MEEG collectively), it has also beenapplied to compute forward solutions for ECoG, for implanted EEG, for cochlear implant stimulation, for tDCSand other electrostimulation settings. In this presentation we detail the features of the latest release ofOpenMEEG.Geometrical models have now been extended to handle non-nested geometries: the various domains muststill have a constant isotropic conductivity but they need no longer be nested inside one another. OpenMEEGsupports CGAL meshing tools (allowing to remesh or decimate existing meshes, or to mesh a levelset). Linearalgebra packages MKL and OpenBLAS are now supported on all platforms (Linux, MacOS and Windows).Interface with python is improved with python wrappers that avoid memory loss. Gifti and VTK mesh formatsare supported, and some visualization tools are provided (VTK or mayavi). More tests have been included,and last but not least, some bugs fixed.
