Features & Capabilities
Finite element solver and Optimization Software is a fully integrated analysis and design optimization software package
- Supports static, normal modes, direct and modal frequency analysis, random response analysis, heat transfer and system buckling calculations
- Structural optimization types include:
- Topology: Design variables are element densities. Allows to carve out the less essential elements on a package space
- Shape: Grid (node) locations are the design variables
- Sizing: Design variables are element cross-sectional dimensions
- Topometry: Element by element sizing optimization
- Topography: Topography optimization is a special case of shape optimization. Allows to generate beads
- Freedom: Grid by grid shape optimization. Allows to generate ribs
- Composite: Thickness, angles and shape variables
- Supports multi-model optimization (MMO) and reliability-based optimization (RBO)
- Supports Additive Manufacturing: GENESIS topology optimization is for Additive Manufacturing. GENESIS can generate optimal shapes and together with Design Studio, the user can automatically generate lattice structures that can be manufactured with 3D printing
- Task Oriented – just follow built-in trails (wizards) for design tasks.
- Multitask – in Design Studio multiple tasks can be performed simultaneously without abandoning the current trail (e.g., add a design variable while creating perturbation vectors).
- Easy Selections – Design Studio is designed to easily select all quantities needed in optimization such as grids, elements, properties, etc.
- Powerful Filters – in Design Studio limit list of data to what is necessary (taking out unnecessary guesses).
