Speeding Up SSFEM Computation Using Kronecker Tensor Products

Archive ouverte : Article de revue

Gaignaire, R | Guyomarc'H, F | Moreau, O | Clénet, S | Sudret, B

Edité par HAL CCSD ; Institute of Electrical and Electronics Engineers

International audience. The spectral stochastic finite-element method makes it possible to convey some random aspects of input data to the output data. However , the system size dramatically increases with the number of input random variables. Using matrix Kronecker tensor products for system solving noticeably reduces the computation time and the storage requirements.

Mac, Duy Hung | 2011-05

The numerical solution of partial differential equations onto random domains can be done by using a mapping transforming this random domain into a deterministic domain. The issue is then to determine this one to one random mapping...
