SIMULIA Tosca Structure is a flexible, modular software system for non-parametric structural optimization that provides topology, sizing, shape and bead optimization optimization. The setup is simple – model parameterization is not necessary. Existing solver input files (ANSYS, Abaqus, MSC Nastran) are used for the optimization.

Tosca Structure is based on market-leading technology and provides advanced capabilities for optimization with nonlinear analysis and fatigue as well as a specific non-parametric morphing approach.

Topology optimization: Innovative, lightweight design concepts

  • Conceptual design for lighter and stiffer structures. Create lightweight, ready-to-manufacture product designs and reduce time-to-market, physical tests, and prototype builds.

Shape optimization: Improved designs for more durability and strength

  • Improve existing designs for more reliable and durable components. Minimize stress, strain, and damage – or any combination of these – by automatic modification of the surface geometry.

Bead optimization: Efficient bead patterns for increased stiffness and reduced noise

  • Improve the static and dynamic properties of shell structures. Generate optimal bead layouts while accounting for manufacturing constraints, complex geometries, and realistic loads.

Sizing optimization: Best static and dynamic behavior through optimized sheet thicknesses

  • Obtain an optimal relation between weight, stiffness, and dynamic behavior, to gain material savings and take advantage of increased comfort.

USE CASE: TOSCA STRUCTURE.TOPOLOGY


Wind turbine mainframe


For larger wind turbines, stiffness and strength requirements are more difficult to meet. A redesign of the mainframe should result in an economic design with optimal vibration behavior.

USE CASE: TOSCA STRUCTURE.SHAPE


Rear wheel carrier


For weight optimization of this chassis component, multiple criteria such as strength, fatigue, plasticity, and stiffness had to be considered.

USE CASE: TOSCA STRUCTURE.SIZING


Body-in-White


Higher eco-efficiency is one of the main targets in the automotive industry. To realize a significant weight reduction of a body-in-white, the optimum balance between weight, stiffness, and dynamic behavior is required.
