It comes with tools for forward and inverse modelling. IGMAS+ has a long history starting 1988 and has seen continuous improvement since then with input by many contributors.

Since 2019, IGMAS+ is maintained and developed at The Helmholtz Centre Potsdam - GFZ German Research Centre for Geosciences by the staff of Section 4.5 – Basin Modelling and ID2 – eScience Centre with strong ongoing support by H.-J. Götze and S. Schmidt from CAU Kiel. The official webpage of IGMAS+ is available at https://www.gfz-potsdam.de/igmas/. Each major version of IGMAS+ will be assigned with a new DOI. Intermediate releases including changelog can be found at
https://git.gfz-potsdam.de/igmas/igmas-releases/-/releases/.
In IGMAS+ the analytical solution of the volume integral for the gravity and magnetic effect of a homogeneous body is based on the reduction of the three-folded integral to an integral over the bounding polyhedrons (in IGMAS polyhedrons are built by triangles). The original algorithm has been extended to cover all elements of the gravity and magnetic tensors as well. Optimized storage enables extreme fast inversion of material parameters and changes to the model geometry and this flexibility makes geometry changes easy. Immediately after each change, model geometry is updated and the field components are recalculated. Because of the triangular model structure, IGMAS+ can handle complex structures (multi Z surfaces) like the overhangs of salt domes very well. It handles remanent and induced magnetisation of geological bodies and was applied to the interpretation of borehole gravity and magnetics.

Modelling is constrained by structural input from independent data sources, such as seismic data, and is essential toward true integration of 3D thermal modelling or even Full Waveform Inversion. Geophysical investigations may cover huge areas of several thousand square kilometres but also models of Applied Geophysics at a meter scale. Due to the curvature of the Earth, the use of spherical geometries and calculations is necessary. IGMAS+ can be used for both flat (regional) and spherical models (global) in 3D.
