Abstract
The paper proposes the approaches which makes it possible to increase a computationally efficiency of the solution of the direct and inverse “multisource” problems of the marine electrical prospecting in the time and frequency domains. These approaches include the special mathematical formulations, algorithms of generating the optimized finite element meshes and grouping the problems corresponding to the different transmitter and receiver positions and time steps. Besides, the paper presents the software implementing these approaches and allowing performing the 3D modeling of the different marine electrical prospecting technologies and 3D inversion of the obtained data with recovering the geometric and electrophysical parameters of the structural parts of the geological model. The software operates in a distributed computer system consisting of the multicore computers connected by a local network. This software includes the manager program providing the data transfer from client to servers, obtaining the results of the calculations, and checking and correct processing the situations of a breakdown of the communications between computers and an emergency shutdown of some computational nodes.
