In this study, we apply an artificial viscosity method to convert unsteady level set (LS) convection equation into LS convection-diffusion transport stabilize the numerical solution of term. Then a novel least-square polygonal finite element is used solve problem. The least-squares provided good mathematical properties such as natural diffusion and positive definite symmetry resulting algebraic...

Over the past few decades, there have been many important achievements on design, research, and development of minimal surface lattice structures. In this work, we propose a modeling method for triply periodic surfaces (TPMS) structures with complex contours. This is based moving elements (MEM) mainly includes following parts: dividing model mesh, solving iso-surface TPMS in model, obtaining st...
