✦ Synopsis

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 regions where small elements are located, the new procedure decreases element distortion considerably, reducing the need for local or global remeshing, and in some cases avoiding it altogether.

## Abstract A sliding mesh method is demonstrated for moving body simulations involving thermal and fluid problems. Static problems with non‐contiguous mesh constructions are also solved using the same methodology. The proposed algorithm employs a parallel implementation of multipoint constraints w
