Tosca is Dassault Systèmes’ industry-leading generative design solution for structural and fluid flow optimization. Built on powerful finite element (FEA) and computational fluid dynamics (CFD) foundations, Tosca allows engineers to automatically optimize shapes, stiffness, flow paths, and structural thicknesses based on performance targets.
Tosca provides significant value by accelerating product development, minimizing material usage, and enabling the creation of lightweight, durable, and manufacturable designs. It is fully compatible with industry-standard solvers including Abaqus, Ansys, and Nastran.
Tosca Structure
Topology Optimization
Remove inefficient material to generate the most load-effective geometry within a defined design space. Ideal for early concept design and lightweight structures.
Shape Optimization
Refine external surfaces to reduce stress concentrations and improve durability, without changing the component’s topology.
Sizing Optimization
Introduce optimized bead patterns in shell components to improve stiffness, increase eigenfrequency, or reduce vibration.
Bead Optimization
- Create bead patterns for shell structures.
- Increase stiffness or eigenfrequency of sheet metal structures.
Tosca Fluid
Innovative Fluid Flow Design
Used for non-parametric fluid flow optimization, Tosca Fluid modifies the internal shape of flow channels to reduce pressure drops, balance flow rates, and improve thermal or acoustic performance — without needing an initial design.
Key Benefits
- Reduces pressure drop and improves flow uniformity
- Minimizes physical prototypes and test iterations
- Accelerates design cycles and time-to-market
- Enables innovative concepts from available design space
- Cuts energy losses and flow-induced noise
Technical Highlights
- Integrates with major CFD tools (Fluent, Star-CCM+)
- One CFD run delivers a fully optimized design
- Handles complex industrial geometries
- Powerful GUI for result analysis and geometry export
Key Benefits of Using Tosca
- Accelerate product development through simulation-driven optimization
- Reduce time-to-market and number of physical prototypes
