## Mesh Update Methods for Simulation of Spinning Mechanical ComponentsThe T*AFSM introduced a number of advanced mesh update methods for computation of moving boundaries and interfaces with the DSD/SST formulation [1-15]. These include the Shear-Slip Mesh Update Method (SSMUM) [6, 8, 10], which was developed computation of flows with objects in fast, linear or rotational relative motion. The SSMUM was first implemented by Masayuki Kaiho (Hitachi, Japan) for objects in fast, linear relative motion. This was applied first to incompressible flow around two high-speed trains passing each other in a tunnel. Compressible flow computations for the same problem was first reported in [6]. Following that, the SSMUM was implemented for objects in fast, rotational relative motion [16-17]. The SSMUM concept can be applied to turbomachinery systems, propellers, helicopter blades, and mixing systems. The figures show the mesh and air pressure on the surface of a helicopter fuselage and rotor at two different instants in time. The simulation was carried out on a CRAY T3E-1200, and was reported in detail in [17]. ## References: 1. T.E. Tezduyar, "Stabilized Finite Element
