SIMULIA TOSCA FLUID

DESIGN AND OPTIMIZATION FOR FLUID FLOW SYSTEMS

TOSCA FLUID
Tosca Fluid is a unique, modular software system for non-parametric fluid flow optimization that enables topology optimization
KEY BENEFITS
with industry-standard CFD solvers. The setup is simple. No model parameterization is necessary, and existing simulation files
(even large scale CFD models) can be used for optimization. Tosca Fluid offers state-of-the-art optimization technology that
helps engineers to develop innovative product designs based solely on a given design space and a defined flow task. No initial
design is necessary, and only one solver run is needed.

TOSCA FLUID FEATURES

Innovative design concepts with reduced pressure drop and enhanced flow uniformity
Topology optimization – conceptual design to create fluid flow devices with reduced pressure drop and / or improved
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.
Create optimized product concepts with increased flow efficiency, which require less physical testing and fewer
prototypes. Achieve a shorter time-to-market and improve your competitive position with state-of-the-art,
eco-efficient designs.

TOSCA FLUID ADVANCED CAPABILITIES*

Mass flow balancing
Flow balancing tasks - 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 (among others).

Reduction of flow instabilities, induced noise and vibration
Flow acoustics optimization - achieve significant noise reduction by eliminating flow instabilities. Design
products with enhanced flow efficiency. Achieve a balanced and noise reduced flow solution for increased
efficiency and comfort. 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 cooling ducts.
* for selected cases - depending on given technical and physical conditions

EXAMPLES OF THE INDUSTRIAL USE OF TOSCA FLUID
Air outlet vent
The redesign of an air vent should result in a new device with
lower pressure loss and improved flow distribution between
driver‘s side and passenger‘s side.
With Tosca Fluid topology optimization, a better design can
be created. By reducing both pressure loss and noise at the
same time, the result is an efficient and comfortable alternative
to the original air vent. With Tosca Fluid technology all
performance objectives for the air vent were met. With less
fan power needed, additional cost savings can be achieved.

Final design

The use of TOSCA Fluid in the redesign process resulted in a
pressure drop reduction of up to 50%, better flow efficiency,
and overall cost savings. For an enhanced comfort, the flow
distribution ratio between driver and passenger was improved
from 40%/60% to almost equal.

Dual stream DOC design concept
Design of a dual stream Diesel Oxidation Catalyst concept that
processes higher gas volumes without extensive pressure drop
—still using conventional 5 2/3 inch monoliths.
To create a space-saving design for flow guiding components
(like flow splitters, diverters, and collectors) a topology
optimization driven design based on an initial design space was
executed. After the optimization, the individually optimized
components were assembled to create a new dual stream DOC
design with significantly reduced pressure drop, enhanced
flow split ratio and high flow uniformity across the catalytic
sections. The resulting design has optimal performance and
improved eco-efficiency.

Using topology optimization, a new and promising DOC
design was generated. The pressure drop has been reduced
by 65% while the flow distribution ratio of the new design
concept improved from 47/53 to almost equal. The entire
design process took only two weeks.

Intecooler intake hose
A new intercooler intake hose design with less power loss was
needed. The redesign with reduced total pressure drop must fit
within the existing package space.
Optimization with Tosca Fluid eliminates existing recirculation
zones and backflow areas which leads to a substantial increase
in energy-efficiency. The new design proposal also meets the
given space restrictions. With only a single solver run needed,
extensive computing time can be saved compared to
CAD-parameter based design and optimization schemes.

The result of the topology optimization provides a 20 %
reduction of pressure drop compared to the initial design.
With a volume change of less than 3 %, TOSCA Fluid
achieved a significant per formance improvement for
the intercooler intake hose.

POWERFUL GRAPHICAL USER INTERFACE
Intuitive and easy to use GUI which allows for fast setup and direct execution of optimization
tasks. Monitoring of the optimization progress with real-time feedback, using industry-standard
CFD solvers. Intuitive postprocessing and geometry generation for optimized design proposals.

Realtime optimization progress monitoring

“With an intuitive set-up and graphical user interface we increase usability and value for
our customers. Intuitive data management , short processing times and a simple result
generation help engineers to maximize flow efficiency, reduce cost and improve reliability.“
