GENESIS is a fully integrated finite element analysis and design optimization software package, written by leading experts in structural optimization.
Analysis is based on the finite element method for static, normal modes, inertia relief, direct and modal frequency analysis, random response analysis, heat transfer, system buckling calculations, sensitivity, composite analysis and nonlinear contact (GAP elements) analysis.
Design is based on the advanced approximation concepts approach to find an optimum design efficiently and reliably. An approximate problem, generated using analysis and sensitivity information, is used for the actual optimization, which is performed by the well-established DOT or BIGDOT optimizers. When the optimum of the approximate problem has been found, a new finite element analysis is performed and the process is repeated until the solution has converged to the optimum.
Genesis is easy to learn, so no special knowledge of optimization technology is required. Many design options are available for users including: shape, sizing, topography, topometry and topology. Shape/sizing and topography optimization typically require less than ten detailed finite element analyses, even for large and complex design tasks. The topology and topometry optimization typically takes twenty or less detailed finite element analyses.
Topology Optimization - is an optimization capability which allows the user to find the best distribution of material. With topology optimization, an optimal structure is generated by carving out material from a given design space, allowing for a given amount of material.
Sizing optimization - is an optimization capability which allows the user to find the best dimensions of any designable elements like bars, shells and composites.
Topometry Optimization – is an unique optimization capability which allows the user to find the optimal distribution of sizing dimensions over the structure. Like topology, this capability can be used to find the optimal places to take out material. Unlike topology, it also can be used to find the best places to add additional material. Element by element sizing optimization, which adds new perspectives to topology and sizing optimization.
Shape Optimization – is an optimization capability which allows the user to find the best shape possible. The software finds the best location of the finite element nodes, which define the shape of the structure.
Topography Optimization – is an optimization capability which allows the user to find the location and shape of bead patterns to stiffen panel structures.
Freeform Optimization – is a new shape optimization capability which allows the user to find the best location and shape of rib patterns that stiffen solid structures (Gird by grid shape optimization). It can also be used to find the best location of grids in any type of structure.
Composite Optimization - is an optimisation capabilty whichallowsthe user to find the optimal ply placements to support all the loading conditions considered. GENESIS uniquely considers strength design limits, allowing engineers to consider all the loading requirements at the key concept stage of structure.
Design Studio for Genesis is a design oriented pre- and post-processor graphical interface for the Genesis Structural Analysis and Optimization Software. Design Studio allows users to display finite element models and to easily create Genesis design data. It allows users to display analysis as well as optimization results.
