Abstract
A Laplacian smoothing of the mesh velocities with variable diffusivity based on the distance from moving bodies is introduced. This variable diffusivity enforces a more uniform mesh velocity in the region close to the moving bodies. Given that in most applications these are regio ns where small elements are located, the new procedure decreases eleme nt distortion considerably, reducing the need for local or global reme shing, and in some cases avoiding it altogether.
