GPU optimized software for forward and inverse gravity problems solution for contact boundary between two layers

Abstract

The paper presents methods overview and software for forward and inverse gravity problems solution for contact surfaces. Forward calculations are improved by introducing the finite elements method. This allows one to calculate the gravity field of shallow boundaries. Inversion is performed by the method of local corrections. Both methods are optimized with CUDA, which significantly increased efficiency. The software CUGRACID is distributed under open license. Usage information for forward and inverse problems solution programs is provided. © 2020 American Institute of Physics Inc.. All rights reserved.
