FINITE VOLUME METHOD FOR THE CALCULATION OF ELECTROSTATIC FIELD OF THE 3-D SPHERE WITH A CUBIC CAVITY

Abstract

The paper examines an approach to finite volume method which is used to calculate the electric field in three-dimensional environment. It is formulated the problem Dirichlet with building of the computational grid on base of space partition, which is known as Delaunay triangulation with the use of Voronoi cells. It is proposed numerical algorithm for calculating the potential, electric field strength and capacitance in the 3-d sphere with cubic cavity. There are presented results of calculations of distribution in the potential space, electric field strength, and capacitance of the 3-d sphere with cubic cavity.
