Developed for: OOO “GeoPhysTechnika”, Saratov, Russia

Purpose: mapping potentials field in the environment

The given development is intended for simulation and calculation of rock conductivity. Its primary purpose is to select the appropriate probe parameters for the adequate mapping potential field in the environment. The library is applicable to 3D axially symmetrical and non-axially symmetrical electrostatics tasks for hybrid high-performance computational systems; compatibility with COMSOL format models is provided.
The work of the library is based on the finite element method (FEM) and is divided into the following stages: computational model setting, computational domain triangulation, FEM computation, post processing. A high operational speed is the main feature of the given development: as computations are parallelized on both CPU and GPU, the computation time here gets lower than with the COMSOL package; furthermore, the maximum error does not exceed 1%.
