Tosca
Topology Optimisation
based on FEA and CFD simulations
The Tosca optimisation suite enables engineers to take full advantage of any improvement potential while leveraging advanced simulation capabilities. Tosca Structure and Tosca Fluid – as leading technologies for structural optimisation and flow optimisation – offer efficient optimisation based on FEA and CFD simulations.
Benefits of Tosca
Reduced Product Development Time
Easy setup of the optimisation task, and a shorter time-to-market with fewer prototypes and physical tests. Tosca is available as integrated software within Abaqus, or through a dedicated standalone interface.
High Quality Simulation Results
Benefit from more realistic results, automatic validation of results, and handling of even complex production/manufacturing requirements. Tosca boasts extensive experience with specific customer applications across various industries around the world.
Improved Competitive Position with State-of-the-Art Designs
Economic design concepts achieve potential savings of weight, material, and design space. Technology and software development at the latest scientific state-of-the-art: knowledge transfer from numerous research projects in highly developed optimisation technology.
Seamless Integration
Tosca integrates seamlessly with leading FEA & durability solvers such as Abaqus, Ansys and MSC Nastran. Tosca Structure can also be combined with Abaqus, fe-safe and Isight. That is the power of the SIMULIA portfolio.

Tosca Structure
Structural topology optimisation coupled with leading FEA tools
Tosca Structure is the market leading technology for the rapid and reliable design of lightweight, rigid and durable components and systems. Using topology optimisation you obtain optimal design proposals already during design concept. Specific detail improvements through shape and bead optimisation respectively make your designs ready for production.
Tosca Structure Key Features:
- Topology Optimisation: Conceptual design for lighter and stiffer structures.
- Sizing Optimisation: Best static and dynamic behaviour through optimized sheet thicknesses.
- Shape Optimisation: Improved designs for more durability and strength.
- Bead Optimisation: Efficient bead patterns for increased stiffness and reduced noise.
- Optimisation module in Abaqus CAE: Define optimisation tasks interactively on 3D Abaqus/Standard models.
- Tosca Extension for Ansys Workbench: Define topology optimisation tasks interactively on 3D ANSYS Workbench models and author.
- Tosca Ansa environment: Define optimisation tasks interactively from within the Ansa environment on predefined 3D models.
- Graphical User Interface: A standalone graphical user interface which supports Abaqus, ANSYS, MSC Nastran FE models.
Tosca Fluid
CFD topology optimisation for high-end CFD software
Tosca Fluid is so far the only available system for topology optimisation of channel flow problems. Starting from an initial design space, an optimised design of a flow channel is determined automatically by Tosca Fluid. With only one CFD solver run an optimised structure with e.g. significantly reduced pressure drop or homogeneous flow is derived. This allows for the first time an economic topology optimisation of industrial large scale flow applications.
Tosca Fluid Key Features:
- Generate reduced pressure drop and enhanced flow uniformity: Profit from full design flexibility to create a design proposal in the initial design phase.
- Powerful graphical user interface: Intuitive and easy to use graphical user interface allows for fast setup and direct execution of optimisation tasks.
- Mass flow balancing: Generate design concepts for a desired flow split ratio with multiple given outlets.
- Reduction of flow instabilities, induced noise and vibration: TOSCA Fluid has been successfully used for components such as climate control components, hydraulic systems, pneumatic components and cooling-ducts.
Main Technologies
Engineers have to develop innovative products in the shortest development time possible. Security, comfort, performance, efficiency, durability and flexibility are some of the manifold requirements that have to be considered. Conflicting targets are complicating the generation of simple solutions.
Design Concept: Concepts in a Virtual Product Development
The product development costs are mainly determined in the early concept phase. The automatic generation of optimised design proposals will reduce the number of product development cycles and the number of physical prototypes. The quality is increased and the development costs are significantly reduced. All you need is the definition of the maximum allowed design space – Tosca helps you to find the design that fits and considers all system requirements.
Design Improvement: Simulation-Driven Design Improvement
Existing designs often need small changes to adapt the design to changes in the external boundary conditions. Using optimisation methods, design changes can quickly be applied and all relevant product requirements can be considered.
Decision Support: Product Knowledge and Decision Support
Due to increasing product complexity, the product development process cannot only be driven by classic analytical methods, experiments and simulation methods. The complexity can often only be coped under use of modern mathematical methods. SIMULIA provides intuitive and user interactive methods to analyse existing datasets from simulation and physical testing.
