Product: Abaqus/Standard
Benefits: The pyramid elements are useful to transition between brick elements and tetrahedra elements during mesh generation.
Description: The new 5-node pyramid elements C3D5 and C3D5H support all of the loadings, material behaviors, and boundary conditions supported by the existing brick, wedge, and tetrahedral solid elements.
