Description
OpenMEEG implements boundary element solutions for simulating electromagnetic fields in the quasistatic regime. Originally designed for the forward EEG and MEG problems (MEEG collectively), it has also been applied to compute forward solutions for ECoG, for implanted EEG, for cochlear implant stimulation, for tDCS and other electrostimulation settings. In this presentation we detail the features of the latest release of OpenMEEG.Geometrical models have now been extended to handle non-nested geometries: the various domains must still have a constant isotropic conductivity but they need no longer be nested inside one another. OpenMEEG supports CGAL meshing tools (allowing to remesh or decimate existing meshes, or to mesh a levelset). Linear algebra packages MKL and OpenBLAS are now supported on all platforms (Linux, MacOS and Windows). Interface with Python is improved with wrappers that allow to pass data to Python without memory copies. Gifti and VTK mesh formats are supported, and some visualization tools are provided (VTK or mayavi). More tests have been included, and last but not least, some bugs fixed.
