MODELLING AND SIMULATION
Designing the Future
GEMMA CHURCH INVESTIGATES HOW MODELLING AND SIMULATION TOOLS ARE USED TO DESIGN NEW COMPONENTS AND SYSTEMS
When designing a component or system, where do you start? In days gone by, designers would
literally go back to the drawing board, using their experience and expertise to develop a new concept. Now, simulation and modelling have unleashed a new paradigm, with a wealth of innovations continuing to push the design tools field forward.
This increase in demand for simulation and modelling techniques comes at a time when advancing digitisation and product complexity are already pushing the boundaries of our current design capabilities. James Dagg, CTO at Altair, said:
‘Increasing product complexity at the part and assembly level is the overriding trend. Leading companies ensure
collaboration between design, engineering and manufacturing bring their innovative products to market faster.’ This intrinsic need for simulation and modelling in the design tools space is a result of advancing digitisation and electrification. Paul Brown, senior marketing director of the product engineering group at Siemens Digital Industries Software, said: ‘If we think about how products have evolved, the role of electronics and software has increased substantially. This situation is the same for the majority of industries, where companies must deliver new concepts to market quickly and in the face of growing product complexity. Simulation and modelling must aid communication between the electrical and mechanical domains to achieve this.’
Simulation and modelling tools must
also be available across the design lifecycle. Dagg added: ‘Because of this increased complexity and stringent time constraints, engineers and designers need to be able to evaluate their products’ manufacturability in the conceptual development phase, evaluating different processes based on their performance and production constraints.’ Such measures not only simplify the design process but also provide extensive cost and time savings for the company and its design teams. Dagg said: ‘Integrating Altair SimSolid into Altair Inspire eliminates the time- consuming and expertise-extensive tasks of geometry simplification and meshing and also provides a single, easy-to-use environment where design, simulation, and manufacturing engineers can make rapid design iterations.’ ‘The same Inspire user experience
