A New Block Preconditioner for Double Saddle Point Systems Arising from Liquid Crystal Directors Modeling
摘要
We develop and investigate a new block preconditioner for a class of double saddle point (DSP) problems arising from liquid crystal directors modeling using a finite element scheme. We analyze the spectral properties of the preconditioned matrix. Numerical results are provided to evaluate the behavior of preconditioned iterative methods using the new preconditioner.
