| Реферат: | eng: The paper addresses numerical modeling of electric and magnetic fields in fiber media generally described by Maxwell equations. Complex microstructures and composite materials in modern optics devices require special techniques to be modeled. These peculiarities are all considered in FVTD method proposed. High computational complexity inherent to multidimensional computations is resolved through parallel computations. For this purpose the decomposition of nonstructured triangular grids and MPT programming model are implemented. The resulting efficiency graphics obtained on HLRS cluster (NEC Xeon EM64T Cluster) show good scalability.In particular case, the simple fiber waveguide can be described by the simplified mathematical model. Nevertheless the computational complexity increases when femtosecond laser inscription with close to critical input power are considered. In order to parallelize these computations the parallel Thomas algorithm for solving tridiagonal linear systems was implemented. The obtained efficiency graphics are discussed.
