Numerical modeling of vector or scalar physical fields is an important tool for analyzing and understanding geophysical methods. In Gravimetry it is no different; the modeling allows studying the gravimetric signal in different situations simulating the execution of surveys. In this context, it is desirable to continually research, diversify and improve gravimetric modeling. I present a new gravimetric modeling methodology for three-dimensional mass distributions, suitable even for models in which the density distribution presents complex geometry. We solved the numerical calculation of the gravimetric signal of an irregular polyhedron, which makes it possible to discretize the subsurface with these elements and calculate the gravimetric anomaly of complex three-dimensional models, allowing the use of widely available 3d mesh producers.
