Merging geometry in Inspire before importing to EDEM

Hi,
I am using EDEM 2025 and Inspire 2025.

I have a model that consists of many different parts in Inspire, when I then import the model into EDEM it becomes many different "geometries". This is a problem since I want to use this model in an optimization like this:

Since the model is imported into different geometries the motion wont move all of them together. Is there a way to group them so EDEM import it as only one geometry?

Just to clarify the tree in Inspire looks like this:

and I am exporting it as a STL file.

Hello @Karl_H,

there is an option to merge geometries in Inspire by using the boolean tool.

Although in this way the combined geometry will lose it's parametrization as all entities will become one. I would suggest to do that on EDEM side. When you are importing all the geometries you have the option of defining parent body.

In this way you can assign all geometries to one parent body which will be the one you are applying the motions to. The rest should move as the are fixed to it.

Hope this helps!

Best regards,
Orestes

Thank you for the answer!

I will use this later in Hyperstudy to optimize the geometry, so I will not be able to do it manually but I found a more in depth video that shows an example to combine the parts to a STL file.
