Add Ons DCS

Model Compliant and Flexible Parts, Account for Force, Gravity and Thermal

 Available for 3DCS Variation Analyst (Multi-CAD, NX, CATIA V5 and V6)


FEA mesh data can be used to visually display deformation, and analyze compliant parts. 

Compliant vs. Rigid Modeling


Traditional variation analysis methods are considered to be "rigid-body" or "non-compliant" modeling; meaning, that every part within  the assembly does not flex or would not be distorted through an assembly process such as welding, clamping or unclamping of an assembly fixture.

While this might be the case with a few machined components, most commodities and materials like sheet metal, plastics, aluminum, etc. can be heavily influenced through the manufacturing processes (both fabrication and assembly), thus changing the dimensional integrity or shape of the part/assembly. Finite Element Analysis (FEA) is used to determine the stresses and displacements in mechanical objects and systems, and is the basis for this leading edge advancement in predictive analysis.

3DCS FEA Compliant Modeler, an add-on module to the 3DCS software solutions, utilizes FEA methods to accurately simulate variation of compliant parts and assemblies within the 3D Variation Analysis model.
