Tosca: Efficient Optimization based on FEA and CFD Simulation

SIMULIA
Tosca - The Optimization Suite
Today’s engineers aspire to develop innovative products in the shortest development time possible. Security, comfort, performance, efficiency, durability, and flexibility are just some of the aspects to take into account. As leading technologies for structural optimization and flow optimization, both Tosca Structure and Tosca Fluid offer efficient optimization based on industry standard FEA (Abaqus, ANSYS, Nastran) and CFD software (STAR-CCM+ and ANSYS Fluent).

The Tosca optimization suite enables engineers to take full advantage of any improvement potential while leveraging advanced simulation capabilities. It creates optimized design concepts to achieve the highest performance, quality, and eco-efficiency in a shorter development time.
Tosca Structures
Tosca Structure is the market leading technology for structural optimization based on industry standard FEA packages (Abaqus, ANSYS, MSC Nastran). It allows for rapid and reliable design of lightweight, rigid and durable components and systems.

Using topology optimization with Tosca Structure.topology you obtain optimal design proposals already during design concept. Specific detail improvements through shape and bead optimization respectively (with Tosca Structure.shape and Tosca Structure.bead respectively) make your designs ready for production. With Tosca Structure.sizing you find optimized sheet thicknesses even for large scale applications with up to millions of design variables. The result are designs with optimum relation between weight, stiffness and dynamic behavior.

The Tosca Structure suite provides key technical benefits, including:

  • Seamless integration with leading FEA & durability solvers
  • Direct use of existing knowledge and models
  • Full design flexibility without time-consuming parameterization
  • Fast and easy creation of design variants without intermediate CAD modifications
  • High fidelity optimization for nonlinear analysis and durability
  • Simultaneous optimization to meet static, dynamic, and thermo-mechanical requirements
  • Handling of complex manufacturing conditions
  • Automatic validation analysis runs and direct data transfer to CAD systems
