Numerical simulation of arterial vascular viscoelasticity flow is an important issue on biological fluid dynamics, which can compensate for its deficiency in vitro experiments. Here, we pay more attention to the efficient numerical methods on arterial vascular viscoelasticity flow. Variational inequality is studied and developed for the arterial vascular viscoelasticity flow without regard to elastic deformation of the coupling. Under the assumption of elastic deformation, the finite element method is applied in simulating deformation of the tissue and arterial wall and the finite volume method is designed on moving mesh to compute blood development flow. For time and spatial discretization, the adaptive stabilized finite element/volume method and large time step method are used respectively. In order to solve the nonlinear and large scale computing, stabilized methods on the lowest order finite elements, multi-scale method, preconditioning post-processing approach are combined, moreover, spliting and decoupled technique, and domain decomposition method are used to develop some high-precision calculation scheme with non-increasing energy, mass conservation, good stability, and strong flexibility properties. We study on the efficient numerical methods for the arterial vascular viscoelasticity flow in order to unify mathematical problem, physical background, and numerical simulation so as to improve the structure of the presented methods to make thre numerical solution not only maintain its physical properties, explain from theoretical point of numerical methods, but also solve the problems simply and efficiently. Furthermore, we provide the new research approaches to simulate arterial vascular viscoelasticity flow, and to develop the nonlinear scientific research and apply to the fluid dynamics in the relevant industries.
