Tosca Solutions

Tosca Structure

Structural topology optimization coupled with leading FEA tools

This is the market leading technology for rapid and reliable design of lightweight, rigid, and durable components and systems. Using topology optimization, you obtain optimal design proposals already during design concept. Specific detail improvements through shape and bead optimization respectively make your designs ready for production.


Tosca Fluid

CFD topology optimization for high-end CFD software

This is the only system for topology optimization of channel flow problems. Starting from an initial design space, an optimized design of a flow channel is determined automatically. Using only one CFD solver, run an optimized structure with, e.g., significantly reduced pressure drop, or where homogeneous flow is derived. This allows for the first time an economic topology optimization of industrial large scale flow applications.

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

Automatic generation of optimized design proposals reduces the number of product development cycles and the number of physical prototypes. All you need is the definition of the maximum allowed design space.


Design Improvement

Simulation-Driven Design Improvement

Existing designs often need small changes to adapt the design to changes in the external boundary conditions. Using optimization methods, design changes can quickly be applied, and all relevant product requirements can be considered.


Decision Support

Product Knowledge and Decision Support

The modern product development process cannot be driven solely by traditional analytical, experimental, and simulation methods. SIMULIA provides intuitive and user interactive methods to analyze existing datasets from simulation and physical testing.
