Finite element method, hand calculation and trial-error than products designed with more durable, can be produced, high quality and low cost, complex geometry designs made it possible to do in computer environment. Nowadays, the finite element method is a widely used tool in almost all industries and it is known that the capabilities and the benefits it provides to the user are well known. In the current century, the subject of optimization becomes more and more important.
Traditionally, topology optimization aims to create new concept designs for the required strength while surface strain and strain strain and fatigue improvements are realized. At this point, manual optimization calculations remain very limited and last longer. For example, computer-aided optimization makes it possible to achieve more economic gains without compromising the quality of a product, as well as to improve the quality without changing the cost of the product or to optimize the design geometry within specified limits. With the application of the theoretical infrastructure in the literature on the finite element method of optimization, Tosca optimization software which is included in the SIMULIA family has emerged. Structure and flow optimizations can be realized with Tosca. It plays an important role in making the design more effective by making modifications on the existing design according to the targets and limits created by the user. The surface optimization technique minimizes stress concentrations by making changes in the details of an existing design. Thanks to its sheet metal thickness optimization / topology optimization capabilities, the optimization goal of Abaqus is defined in Abaqus, which is based on many variables such as increasing the weight, increasing the strength and making changes in the product topology by taking into account the production techniques. On the other hand, Tosca, in addition to ABAQUS; It supports the model outputs of different finite element software such as Ansys, Nastran, Patran and Pro-engineer.
Tosca Structure is the leading SIMULIA solution for designing more economical, durable and lightweight structures and improving existing designs. Tosca Structure.topology, Tosca Structure.sizing, Tosca Structure.shape and Tosca Structure.bead four different optimization solutions to the solution consists of four different modules.
Tosca Structure topology: It is the optimization technique used at the beginning of the product development process. Lighter and more robust concept designs can be achieved with topology optimization. Using Tosca Structure.topology significantly reduces the time it takes to introduce innovative designs.
- Allows you to create lightweight and customizable designs.
- Accelerates the engineering phase by shortening product design and testing processes.

Tosca Structure sizing: Sizing, in other words, calibration optimization is used to optimize the weight, strength and dynamic behavior of sheet metal structures within the limits determined. Sizing optimization allows you to design ecological and more comfortable structures while saving material.
- It is used to create sheet metal structures optimized for automotive, wind energy and aerospace applications.
- Optimal weight, strength and dynamic behavior relationships for advanced ergonomics to identify and understand.
- The thicknesses of sheet metal structures can be optimized over a region or on finite elements.

- The calculation period varies directly with the number of design variables used.
- Improves eco-performance.
With the Tosca structure, calibration optimization is intended to design complex structures that will provide optimum performance under specified loading conditions. Without changing the general shape of geometry, the optimization of sheet metal thicknesses, weight, strength and dynamic performance due to their interrelationships gives the user the opportunity to present innovative designs.
Tosca Structure shape: With Shape optimization module, existing designs can be made more suitable and durable. The stress, strain and strength optimization on the specified surface can be performed automatically.
Improves product quality by minimizing local stress build-up.
Increases product durability and extends product life.
Existing finite element model's load and boundary conditions can be used as it provides significant benefits in terms of modeling time.
Thanks to the direct non-parametric approach, the time spent parametrizing the model is long.
The shape optimization technique is used to develop an existing product. With the Shape optimization module, the product quality is increased and the fatigue life is extended by making relatively small changes on the design.
Tosca Structure bead: Creates folds, twists and patterns on the sheet metal to meet the design requirements. Strength / weight, dynamic behavior and fatigue life etc. The criteria can be optimized as singular or unified.
