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.

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.
