Abstract: Abstract A multigrid pressure correction scheme suitable for high order discretizations of the incompressible Navier–Stokes equations is developed and demonstrated. The pressure correction equation is discretized with fourth-order compact finite-difference approximations. Iterative methods based on… read more here.

DOI: 10.1016/j.polymer.2017.09.062
Abstract: Abstract We investigate two coarse-grained models of a cis -polyisoprene melt. The bonded interactions which are used in both models are derived by Boltzmann inversion of the probability distributions of the bonded variables in a… read more here.
