A block preconditioner with two parameters for double saddle point systems in liquid crystal director modeling
Mehdi Makhdomi, Davod Khojasteh Salkuyeh, Morad Ahmadnasab
This paper introduces a novel block preconditioner for a class of double saddle point systems arising from the finite element discretization of liquid crystal director modeling. We…
