Finite Elements and Functional Structures
Functional structures require a larger scale mesh than smaller models.
Simulation of a large structural assembly requires specialized techniques to generate an appropriate mesh.
When a functional structure model is converted into a mesh, the panels and profiles are converted to shells (Shell Section_Panel Name-Plate Name) and beams (Beam Section_Panel Name-Stiffener Name). The app creates shell section properties for each panel. If the panel has stiffeners, the app also creates coating 1D mesh parts. A panel might also consist of multiple plates, each with different thicknesses or materials. In these cases additional shell section properties are created for each change of thickness or material.
Similarly, the app creates beam section properties for all profiles (stiffeners). If a profile has different sections or materials, the app creates additional beam section properties. The beam profiles for stiffeners use the ProfileType parameter (if one is defined) or the section name from the original structure to create the correct profile shape.
