Abstract: To meet the accuracy requirement of surface three-dimensional (3D) Magnetic Resonance Spectroscopy (MRS) forward modeling. Hammer integration algorithm was proposed based on unstructured non-uniform tetrahedral mesh. First, finite element method was used to calculate the 3D magnetic field in the subsurface, and the sensitivity kernel expression was deduced. Then, to overcome the shortcoming of conventional mesh grid, that the precision becomes poor as grid size is large, while smaller grid size leads to enormous calculation task, Hammer integration was applied to calculate the kernel function with conventional grid. Synthetic results including 3D kernel function and aquifer models show that, using Hammer integration, higher precision can be achieved with fewer grids and nodes. The forward model can be calculated efficiently.

Key words: technology of instrument and meter, Hammer integration, surface MRS, high precision, forward modeling, kernel function
