SIMULIA Tosca Structure - Topology Optimization Process

Topology optimization

Conceptual design for lighter and stiffer structures. Create lightweight, ready-to-manufacture product designs and reduce time-to-market, physical tests, and prototype builds.

Shape optimization

Improve existing designs for more reliable and durable components. Minimize stress, strain, and damage – or any combination of these – by automatic modification of the surface geometry.

Bead optimization

Improve the static and dynamic properties of shell structures. Generate optimal bead layouts while accounting for manufacturing constraints, complex geometries, and realistic loads.

Tosca Fluid

CFD Topology optimization for high-end CFD Software


Generate reduced pressure drop and enhanced flow uniformity

Profit from full design flexibility to create a design proposal in the initial design phase. Achieve design goals using the available design space and achieve fast turnaround from analysis to design, with a single CFD solver run.


Powerful graphical user interface

Intuitive and easy to use graphical user interface allows for fast setup and direct execution of optimization tasks. Monitoring of optimization progress with real-time feedback, using industry-standard CFD solvers. Intuitive postprocessing and geometry generation for optimized design proposals.


Mass flow balancing

Generate design concepts for a desired flow split ratio with multiple given outlets. Achieve an optimized flow distribution for maximum comfort and energy efficiency. Typical applications for flow balancing are HVAC components, flow splitters, and heat exchangers.


Reduction of flow instabilities, induced noise and vibration

TOSCA Fluid has been successfully used for the design of noise and stability-sensitive components such as climate control components, hydraulic systems, pneumatic components and coolingducts.
