What element (3D elements, shell element) libraries are available in GENOA?
A- GENOA utilizes NESSUS/MHOST/MINUTES FEM codes that have extensive libraries of elements. GENOA progressive failure analysis module only utilizes 3D 8-noded brick and thick shell elements at the moment. Q-Can you provide brief explanation or references for a nodal based finite element code? What is the basis of this formulation? Is the basis virtual work, a mixed variational principal or something else? A1 The reference s for the nodal based FEM is not new. It was developed throughout years as the iterative algorithms to develop continuos stress field such as CANTIN, Loubigang, Touzot (1978) can be identifed as mixed finite element method. Also further development by Zienkiewicz, Violtte, Nakazazawa, Toyoshima (1984). A-2 The global-local analysis procedure referred to as subelement refinement is developed under the frame work of mixed iterative solution Algorithmic description of the mixed iterative method includes variations for the quasi static, transient dynamic and buckling anal
