Shell Model Strategies using Local Domains
Shell models are models that are made up primarily of shell elements, namely, quads, and trias. In general, a shell model represents many parts, each with numerous features such as holes and edges, and connected together using 1D elements such as bars and rigids.
- Moving the handles on the part to new locations
- Moving the global handles around the parts to new locations
- Altering the radius or curvature of curved edges of the parts, or mapping the nodes of a part to line or surface data
For most models you only need to create 2D domains for the entire part, but you can also add a global domain and global handles for shape alterations of a general nature.
