Parallel application package Helmholtz3D

The paper present parallel application package Helmholtz3D, which allows to compute three-dimensional time-harmonic electromangetic fields propagating in domains with complicated geometry. In order to solve systems of linear algebraic equations (SLAEs) with complex ill-conditioned non-hermitian matrices arising in the finite element discretizations, the package uses state-of-the-art iterative methods in Krylov subspace combined with original parallel preconditioners. Package approbation was performed on the series of model and real-life problems of electromangetic field computation in the microwave devices and well logging problems.
