Abstract EN
For block-tridiagonal linear system of equations, a variant of tangential filtering preconditioners is proposed in this paper.
The new variant is based on a twisted block factorization along with certain filtering property.
For practical usage, a class of composite preconditioners tested, which are constructed by combining the twisted tangential filtering decomposition preconditioner with the classical ILU(0) preconditioner in a multiplicative way.
The performance of the new preconditioners is compared with other classical preconditioners; the superiority and the weakness of the preconditioners are pointed out.
