This white paper explores and analyzes various strategies to improve the efficiency of rotor dynamics analysis using high-performance computing (HPC) with distributed memory parallel (DMP). We will examine the potential performance gains two distinct parallelization methods offer: distributing independent job steps across various processors and solving each individual step using multiple processors. The release of Simcenter™ 3D software version 2512 is used for this purpose. Simcenter 3D is part of the Siemens Xcelerator business platform of software, hardware and services.
