I tried creating bonds at the start and at a fixed time, but I haven’t been able to produce bonded particles. I followed an online tutorial (PDF attached), but couldn't replicate the bonded behavior shown. I’m also attaching my EDEM files for reference
Hi,
Which version of EDEM do you have? You're using an older tutorial, the latest tutorials are here:
Although we don't have the same tutorial any more.
In the tutorial from 2019 it uses the older bonded model (bonding V1 rather than V2) which has the input of Bonded Disk Radius. A length value. 5 mm in this case.
The current version of the bond model doesn't have the Radius value rather a Scale value.
In your case it's set as a scale of 5. This is 5x particle radius (which is 5 mm). So converting the values this is actually a bond radius of 25 mm making the bonds extremely stiff, requiring a much lower time-step.
If you input a bond scale of 1, (which equates to bond disk radius of 5 mm as its 1x radius), then you see the behaviour you expect.

Thanks. It worked
