Abstract

This paper describes an overset approach that comprised virtual boundary-layer-like near-body grid coupled with an off-body adaptive mesh refinement far-field mesh for viscous fluids simulations. Unlike most a priori grid generation systems for the Reynolds-Averaged Navier–Stokes equations, the strand meshing paradigm is automatic, fast and requires little memory to provide boundary-layer coverage. In addition, the stacks of elements implied by the strands can be used to the simulation’s advantage, where they naturally provide a line direction for semi-implicit solving.
