Shape optimization of viscous flow field considering fluid-structure-interactive
Nihon Kikai Gakkai ronbunshu, 2021 This paper presents numerical solution to a shape optimization of viscous flow field for stationary fluid-structure-interactive (FSI) fields. In the FSI analysis, a weak coupled analysis is used to alternately analyze the governing equations of the flow ...

Identification of muscle activity in tongue motion during swallowing through medical image data
Journal of Biomechanical Science and Engineering, 2021 This paper presents a formulation to identify muscle activities from the variation in shapes of organs during swallowing. We assume that each organ consists of a three-dimensional hyperelastic body, and the contraction movement of the muscle is caused by

A New Expanded Mixed Element Method for Convection-Dominated Sobolev Equation
The Scientific World Journal, 2014 We propose and analyze a new expanded mixed element method, whose gradient belongs to the simple square integrable space instead of the classical H(div; Ω) space of Chen’s expanded mixed element method.

A Novel Characteristic Expanded Mixed Method for Reaction-Convection-Diffusion Problems
Journal of Applied Mathematics, 2013 A novel characteristic expanded mixed finite element method is proposed and analyzed for reaction-convection-diffusion problems. The diffusion term ∇·(a(x,t)∇u) is discretized by the novel expanded mixed method, whose gradient belongs to the square ...
