SIMULIA Tosca

SIMULIA TOSCA – TOPOLOGY OPTIMIZATION BASED ON FEA AND CFD SIMULATIONS

The Tosca optimization suite provides fast and powerful structural and flow optimization solutions based on FEA and CFD simulations and consists of two products: Tosca Structure is for optimized structural designs, and Tosca Fluid provides optimized fluid flow design concepts.

Tosca Structure delivers powerful optimization solutions for design of lightweight, stiff, and durable parts and assemblies within shorter development cycles to maximize performance, minimize material and weight, and discover new design possibilities. Tosca Structure offers functionalities for topology, shape, bead and sizing optimization.

Tosca Fluid enables topology optimization-driven design concepts for fluid flow systems and components. Use its capabilities to create innovative design ideas automatically for a defined flow task and available package space. Tosca Fluid’s unique technology helps you achieve the highest flow performance, quality and eco-efficiency.

Tosca Structure - Structural topology optimisation 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.
