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 with an efficient node‐in‐mesh search procedure. A simple method for treating the problem of partially covered/exposed element surfaces is also summarized. Several examples of static and dynamic thermal conduction and viscous flow problems illustrate the algorithms. Published in 2004 by John Wiley & Sons, Ltd.
