Additional complexities with material response are enhanced with tools that enable fluid–structure interaction (FSI). Examples include a high-speed projectile moving though a liquid (shown here) or movement of a structure from a blast wave. Sports equipment design using composite materials Virtual prototyping, from CAD to blow molding to drop-test analysis High-quality mesh generated in ANSYS Workbench using automatic multi-zone method A critical requirement for efficient and accurate explicit analysis is a high-quality mesh. Our explicit products benefit from integration in the ANSYS Workbench environment, which includes powerful automatic mesh generation. You can create high-quality hex (brick) elements for more complex geometries using multi-zone meshing, a standard tool within Workbench that automatically decomposes more complex geometries into parts that can be swept to create hex elements. Some geometries, especially those created for manufacturing and imported from CAD data, are too complex to be swept to produce a full hex mesh. Tetrahedral (tet) elements can accurately represent small portions of a part's geometry that cannot be swept. An ANSYS explicit special tet-element formulation called nodal-based strain (NBS) eliminates shear locking, a problem encountered with traditional tet elements. Accurate tet elements make it easier to create working meshes that can represent complicated geometries. 5 Courtesy Sandia National Laboratory.
