TOSCA is the non-parametric optimization solution within the SIMULIA portfolio, designed to accelerate the development of lighter, stronger, and more efficient products. Based on FEA and CFD simulations, it enables the exploration of innovative designs without starting from a predefined geometry, thanks to powerful topology, shape, bead (surface reinforcement), and sizing optimization algorithms.
TOSCA
Efficient optimization based on FEA and CFD simulations.
TOSCA works directly on the finite element mesh, without the need for CAD remodeling. It is available as a standalone solution or integrated into the 3DEXPERIENCE platform, and it enables performance maximization, material usage minimization, and reductions in weight, cost, and validation time for structural and flow components.
Key features of TOSCA
Topology optimization without CAD reconstruction
Works directly on the finite element mesh, avoiding the geometric remodeling process and accelerating design cycles.
Weight reduction while maintaining structural integrity
Identifies areas where material does not provide structural value so it can be removed, ensuring lighter components that are just as safe.
Lower material usage and production cost
Reduces material consumption from the initial design stage, promoting more sustainable and cost-effective manufacturing processes.
Improved structural performance from early stages
Enables optimization of the product’s shape and strength from the conceptual phase, reducing errors and subsequent rework.
Seamless integration with Abaqus and 3DEXPERIENCE
TOSCA results integrate easily with simulation and collaboration environments such as Abaqus and the 3DEXPERIENCE platform, enabling full traceability.
Benefits of topology optimization with TOSCA
More innovative designs from the conceptual phase
Enables the creation of entirely new shapes driven by structural performance.
Fewer iterations, greater agility
Reduces cycles between design, simulation, and validation, optimizing the entire process.
Weight reduction without compromising safety
Ideal for sectors seeking efficiency without sacrificing structural integrity.
Preparation for additive manufacturing
Generates complex structures optimized for 3D printing or advanced manufacturing.
Improved performance under fatigue or cyclic loads
Increases the service life of components exposed to repetitive stresses.
Types of optimization with TOSCA
TOSCA technology makes it possible to apply different optimization approaches, adapted to each structural or flow design need:
Topology optimization

News and trends around TOSCA
What is non-parametric optimization and why is it revolutionizing engineering?
Most engineers are used to optimizing their designs by modifying parameters: lengths, radii, thicknesses… But what if there were a way to optimize without relying on CAD? That is the basis of non-parametric optimization, and solutions like SIMULIA’s TOSCA are proving...
From generative design to additive manufacturing: the key role of topology optimization
3D printing has opened up new design possibilities. But… are you really taking full advantage of its potential? If you design the same way as always and only change the manufacturing method, you are missing out on a major advantage. One of the greatest allies of...
Why are your designs overdimensioned (and how can you avoid it without taking risks)?
In engineering, fear of failure often translates into excess material. And that costs money. Sound familiar? Designing with large safety margins is common, but also inefficient. This is where topological optimization comes into play. Topological optimization makes it...
