Abstract This work presents the development of an explicit/implicit particle finite element method (PFEM) for 2D modeling metal cutting processes. The purpose is to study efficiency implicit and explicit time integration schemes in terms precision, accuracy computing time. formulation marching developed, a detailed on solution steps presented. PFEM remeshing procedures insertion removal particl...

This paper presents a new strategy to deal with the excessive diffusion that standard finite volume methods for compressible Euler equations display in limit of low Mach number. The can be understood as using centered discretizations acoustic part and stabilizing them leap-frog-type (“sequential explicit”) time integration, fully explicit method. integration takes inspiration from time-explicit...

We numerically investigate the pulsatile flow and heat transfer of a micropolar fluid through a Darcy-Forchhmeir porous channel in the presence of wall transpiration. We use the central difference approximations for the spatial derivatives, whereas the time integration has been performed by employing the three steps explicit Runge-Kutta method to obtain the numerical solution. It i...
