Ask the Expert – Analysis of Large Assemblies Using Component Mode Synthesis (CMS) Technique in ANSYS Workbench and MAPDL
The ever increasing computational power enables us to solve larger FE models but these are still often limited to simulation of sub-assembly level models. Analyzing the complete system, like full-vehicle vibration analysis, full data-center-rack vibration analysis, is often a challenge due to enormous size of such complete models. Component mode synthesis is a technique to analyze very large systems with limited computational resources. This technique has been successfully used in fields like aerospace, automobile and electronics packaging industry.
