Challenge: A change in mindset
The use of computerized optimization tools is largely foreign to the field of architecture. Søndergaard observed that the principal reason for this was “conservatism in the architectural industry toward embracing CAE as constitutive design tools,” a reluctance to lose design control to the optimization software.
The Unikabeton project would be one
of the first academic research projects
to address the use of topology optimization in architectural design. The payoff of the team’s experiments could be significant, since CO2 emissions from the production
of concrete produce 5 percent of total
Since their first Australian SAE Student Racing competition in 2000, the Monash Motorsport team has steadily improved the performance of their race car. The results speak for themselves: six consecutive victories in the Australasian competition, a strong performance in the European Formula Student competitions plus a current number 7 world ranking.
This success is based on a strong fundamental engineering understanding, innovative concepts and a passion to perform at the highest level. Recently the students discovered the benefits of combining Altair‘s OptiStruct optimization technology and 3D printing. Based on an initial prototype rear hub design from the 2013 car, the team proceeded to pursue titanium front hubs and uprights to decrease the car’s unsprung mass. This was a tough challenge, since the former design was already made of lightweight aluminum. To tackle this, Monash Motorsport employed Altair’s optimization technology OptiStruct to design and optimize a titanium upright, which was then produced using additive manufacturing technology from CSIRO. As a result, the students were able to reduce the component’s weight by a further 30 percent whilst maintaining the component stiffness and reducing the development time and costs.
Formula SAE is a competition between university student teams, organized by the Society of
Automotive Engineers. Each student team has to design, build, test, and promote a prototype,
which is then evaluated in eight types of tests, ranging from pure performance and design
to advertising and presenting the vehicle. The worldwide competition takes place during
nine official events in four continents. All official events are subject to a single technical and
sporting regulation. The basic idea of the Formula SAE is that a fictional company engages
the team to realize a prototype with characteristics in accordance with the regulation, which
occupies the market segment dedicated to the non-professional races autocross.
One of the competing teams is SquadraCorse, the student team from the Politecnico di Torino,
Italy. In the development of their cars the team applies Altair‘s HyperWorks suite, in particular
HyperMesh for model creation as well as OptiStruct, the finite element solver and optimization
tool of the suite, which helps them to create better and lighter components.
This session will highlight composite modeling in HyperMesh and optimization using OptiStruct. We will focus on ply-based modeling and explore Altair’s three step optimization process. The key aspects that will be covered are ply and laminate creation, freeshape optimization setup to minimize compliance include some manufacturing constraints, size optimization as it applies to ply composite optimization and finally the ply shuffling optimization.
This session will highlight the capabilities of Altair’s award winning solver technology found in OptiStruct. Live demonstrations will feature the Linear Analysis capabilities as well as the multi-disciplinary Optimization capabilities found in this industry leading software. Linear static, modal and buckling analysis as well as topology, topography, size, shape, free size and free shape optimization techniques will be shown.

Attendees will see live demonstrations of the advanced geometry handling, meshing, and universal analysis setup capabilities of HyperMesh and the power and ease of use of the unique post processing capabilities of HyperView.
In this session, Marc Ratzel will give a quick overview of automotive aerodynamic studies before presenting HyperWorks tools in action. Amongst other topics this will include model preparation, design changes using morphing, solver technology (Navier-Stokes as well as Lattice Boltzmann) and shape optimization.
In this session, Altair’s Rahul Ponginan will be highlighting the optimization driven design process using solidThinking Inspire. We will be learning how to create/import geometry, then proceed to set up the model for topology optimization, analyse the design concept generated and then recreate geometry for final design. In addition Rahul will highlight how you can develop early stage layouts for space frame structures using topology optimization within the Inspire software.
