Code description

Problem	Code name		Notes
1D Inversion	Airborne Ground	AirBeo Beowulf
2D Geology	Airborne Ground	ArjunAir Arjuna	2.5D (2D geology, 3D source) finite elements for models where the geoelectric section varies slowly with respect to strike.
3D Thin sheets	Airborne Ground	LeroiAir Leroi	Thin sheet integral equations for 3D plates with any orientation embedded in layered earth hosts.  This code can also be used to forward model layered earths.
3D rectilinear prisms	Airborne Ground	MarcoAir Marco	Volume integral equations with pulse basis functions for 3D prisms embedded in a layered earth host; automated group symmetry reductions for faster operation; suitable to conductivity contrasts of 1:300.  The code can also be used to forward model layered earths.
3D Complex but compact	Airborne Ground	SamAir Samaya	Compact finite elements for limited 3D domains in a layered earth host, including topography and high contrast unconformities.
3D Complex full domain	Airborne Ground	LokiAir Loki	Edge element finite elements for 3D full domains, including topography and high contrast (1:1 000 000) unconformities.
