MODELLING AND SIMULATION


”We really see that we need to focus on mixed multiphysics simulations where we add more and more physics to our simulation portfolio”


through the engineering V. Going down in the development phase and going up in the verification and validation phase,’ Schramm added. ‘We really see that we need to focus


on mixed multiphysics simulations where we add more and more physics to our simulation portfolio. Then of course computational performance is key, so you really want to optimise your structures and products so we need additional performance. And then of course you need pervasive optimisation, adding optimisation to any of these tools can help you to make quick design decisions,’ said Schramm. Schramm noted that engineering

showcase of the event featured solutions of more than 20 Altair Partner Alliance members, software and hardware allies as well as two stages for product demos: one for the latest versions of the Altair HyperWorks and Altair Inspire product suites – including Simsolid – and one for Altair Partner Alliance member demos. Altair CTOs Dr Uwe Schramm and


James Dagg delivered a keynote presentation entitled: ‘The World is Built on Engineering’, which illustrated the power of Altair’s simulation technology through several practical examples applied to some of the most common product development challenges. Starting with simulation in the early


phases of concept design, designers can take advantage of CFD simulation to explore and validate how different designs impact the aerodynamic performance of a vehicle. Conference attendees were shown how complex, detailed nonlinear airframe simulations can be modelled

and performed quickly and accurately. The presenters will also explain how multiphysics problems like e-powertrain development can be solved with a model- based development approach, which considers electrical and electro-magnetic simulation of systems and sub-systems. During the presentation Schramm


noted that Altair has been developing solver solutions since around 1992 when Optistuct development was started. Then in 2007 the company acquired Radioss technology which was ‘the real kick off for solver development’. ‘In the last five years with the acquisition of electromagnetics technologies Feko and Flux we really can now simulate a complex world of systems with system simulation tools, manufacturing simulation and so on,’ stated Schramm. ‘If you look at the capabilities that we are


developing for the design of electric motors and electrical machines such as self-driving cars, you can see that we provide an entire solutions portfolio throughout development


is becoming increasingly pervasive. ‘Engineering is in almost everything we touch, a part of every human experience. It’s in the planes and trains we travel in, the cars we drive and the appliances we use every day.’ However, engineering advanced


products requires a meticulous, multiphysics development process, in which products are simulated, optimised, and verified many times to ensure the highest quality. Enabled by a broad simulation portfolio, and the effective utilisation of high-performance computing, Altair’s platform aims to address all simulation needs throughout the product lifecycle. ‘We have assembled an entire


multiphysics systems simulation portfolio starting with structural, crash and safety impact simulation, thermal analysis, fluid flow, manufacturing and electromagnetic simulation,’ said Schramm. ‘We are not creating the mother of all solvers in this technology, we are connecting the multiphysics into the design problem and link this through optimisation technology.’
