Paralelizace generování vstupních dat ve FETI metodách

Abstract

In this diploma thesis we deal with an effective parallel input data generation for FETI (Finite Element Tearing and Interconnecting) methods. In FETI methods the original problem, defined on a large body, is partitioned into a number of smaller problems defined on the subdomains. These smaller problems are solved in parallel. To generate the input data effectively in parallel we use the libMesh library. This open-source software library is a preprocessing tool for the numerical mesh-based simulation of partial differential equations on serial and parallel platforms, using the finite element method. Our implementation of data generation is connected to FLLOP library to perform the numerical experiments on Anselm supercomputer. The scalability of our implementation is tested on the academic benchmark from the linear elasticity.
