Small features, big impact #1 – DEMplus

Over the next few weeks, we’d like to invite you to discover some of the features of our software that are perhaps a little less well-known but are certainly worth exploring. In short, small features with big impacts!

In this first instalment, we’ll be focusing on the feature for splitting and merging 3D objects in DEMplus.

This feature is particularly popular with users, as it allows you to adjust the level of detail of 3D objects without having to use third-party CAD software. This represents a significant time-saving ⏳!

But in practical terms, what can you do with this feature?

An individual 3D object has its own characteristics (mass, volume, surface area, etc.). It is often made up of several sub-objects assembled during its design.

The split function allows these sub-objects to be made independent; in other words, for each sub-object, its characteristics are automatically recalculated and it becomes an individual 3D object in its own right, with its own characteristics.

Let’s take the example shown below. On the left, we have a single object representing an assembly consisting of pipework and valves.

If, for example, we wish to simulate the replacement of a particular valve, the level of detail of the 3D object is not suitable. We therefore need to separate these elements in order to carry out our simulation.

After separation, each object – represented by different colours in the image on the right – is individual and can be processed separately, which now allows us to simulate the replacement of the desired valve.

Merging, on the other hand, is the reverse of the separation operation. It allows you to merge several objects into a single one (the characteristics of the resulting object are also automatically redefined), with the same aim of adapting the level of detail to the analysis you wish to carry out.

Pretty handy, isn’t it?
