ST7-R3.50.20.11 Creating Interface Elements between Coincident Geometry
This Webnote illustrates operations and tools for creating interfaces between component parts, such as is required for the analysis of contacting bodies, or simply for disconnecting parts that have been zipped together. Although the physical parts may actually be coincident and may have been modelled in that way in a CAD program, for FEA purposes it is often necessary to introduce a small physical gap between the parts so that contact or other interface elements may be inserted.
