#SOLIDTHINKING INSPIRE OPTIMIZE ADD MATERIAL TO RESULT SOFTWARE#
With topology optimization, you define the loads and constraints, specify what space the part has to fit into, then, when you run the simulation, the software will tell you what shape the part should be in order to satisfy constraints like minimum weight or maximum stiffness. With FEA, you define the shape of a part, add loads and constraints, then run the simulation, to see if you got the shape right. The best way to understand topology optimization is to compare it to FEA. Rather, I think structural topology optimization might be it. While I’m actually a big fan of moving simulation up in the product development process, I don’t think any of today’s CFD or FEA programs are likely to be the killer-apps for upfront simulation.
Still, most designers struggle with figuring out boundary conditions, and determining whether a part requires linear or non-linear analysis (but then, analysts have been known to struggle with these issues too.) The situation with FEA is somewhat better, as being able to run linear static analyses while designing a part can be pretty helpful to designers. And, third, many designers don’t see CFD as their job-they see it as an analyst’s job. Second, many designers don’t have the knowledge required to know whether or not they’re getting good results with CFD. The problem I see is that there are some fundamental requirements to make this democratization idea work: First, you need to offer something that designers actually need second, you need to offer something that designers can actually get good results with and third, you need to offer something that actually helps those designers do their job better.Īt the risk of sounding cynical, let me give some examples of things that haven’t worked as well as the vendors would have liked. While everyone seems to agree that democratization involves making simulation more available (particularly to designers), and more usable earlier in the development process, they don’t necessarily agree on many of the details.
In fact, Googling the term leads to a treasure trove of results-and shows that each of the CAE vendors seem to have entirely different ideas about what democratization involves. Most of the big CAE vendors are enthusiastic proponents for the democratization of simulation.
