Definition
Computational methods, like the boundary element, finite element, or finite volume methods, are numerical discretization methods that can be used for high-resolution gravity field modeling. They are efficient to solve the geodetic boundary value problems in a space domain. To obtain high-resolution numerical solutions usually lead to large-scale parallel computations that can be performed using high-performance computing (HPC) facilities.
Introduction
A determination of the Earth’s gravity field is usually formulated in terms of the geodetic boundary value problems (BVPs). There exist various numerical approaches to solve such potential problems. In geodesy, the spherical harmonics (SH) based methods are usually used for global gravity field modeling. They solve the problem in a frequency domain, and nowadays, they have become a very efficient and sophisticated tool. A recent development of high-performance computing (HPC) facilities has brought new opportunities for...
