Geoceles

Geoimaging tool for small celestial bodies

Geoceles (© 2018 Sampsa Pursiainen) is a simple tool for finite element based forward and inverse simulations in geimaging of small planetary bodies. With Geoceles, one can segment a realistic multilayer geometry and generate a finite element mesh, if triangular surface grids (in ASCII DAT file format) are available. The current version also allows using a graphics card to speed up the mesh segmentation as well asforward (lead field) and inversion computations. Geoceles inherits from the Zeffiro Interface for Brain Imaging (© 2018 Sampsa Pursiainen). More instructions can be found at:
