Speeding up in SSFEM computation using Kronecker tensor products

Abstract : Spectral Stochastic Finite Element Method (SSFEM), 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 reduces noticeably both the computation time and the storage requirements
