What is Enventive?

February 3, 2021

We know that for mechanical design tolerance stack-up analysis is really important for quality in manufacturing. It also has an impact on performance. This is where Enventive can really make a difference.

What is Enventive?

We’ve talked about simulation tools and tolerance analysis tools. But have we talked about them together? Let’s talk about Enventive.

We know that for mechanical design tolerance stack-up analysis is really important. You specify variation within individual components. You roll that up to an assembly and see what the impact will be. You might have a whole bunch of parts that are conforming, but when you put them together they might not overall.

It’s important for quality in manufacturing, but it also has an impact on performance, say structural analysis and other types of things. This is where Enventive can really make a difference

How Does Enventive Work?  

So how exactly does it work? So you start off either by bringing in a 3D model from your CAD application, or you can sketch and develop geometry directly within Enventive. Once you have that definition, then you can add the variability that you have on measured dimensions, as well as any loads and constraints and the other typical things that you would do to set up a structural analysis.

Then you run the analysis. Not only do you get insight on the impact on conformance to manufacturing specifications, like the tolerances, but also you get insight into the performance of that design over the range of variation.

What’s Unique about Enventive?

So why is this a big deal? There are lots of tools out there that are good for the validation of decisions. There are lots of good tools for documentation of the design. So once you have a full 3D model, you can accelerate how quickly you can create documentation and use that productivity.

There are some tools out there that will help with design decisions and this one falls clearly in that category. Although you can use it for validation too, the big difference here is that you can use it for decision-making. You can insert variation into your design. You can see how it affects manufacturing in terms of conformance. You can understand the impact that it has on performance in terms of structures and other types of engineering physics.

So in this way, it really is a pretty important capability. Because if you don’t get the design, right, it’s going to affect you sooner or later in the development process, whether it’s prototyping and testing, or getting to manufacturing and what have you.

This is a tool that’s really different. I haven’t seen this mix of tolerance stack-up analysis and performance analysis in terms of structures, and it really can have an impact on making better designs.
