Linear Dynamics Finite Element Simulation Using Virtual Parts in Catia v5

Abstract

The origin of the virtual parts in Catia v5 is traced back to the RBE elements (Rigid Bar Elements) in the NASTRAN program. The focus of this paper is to explore the functionalities of such elements in linear dynamic problems utilizing Catia v5. Several FEA benchmarks or case studies employing Rigid virtual part and Rigid Spring virtual part under commonly applied boundary conditions are provided. The advantages and disadvantages of these tools are discussed to help the software users choose the right strategy in modeling their structure based on the requirements and goals in mind.
