Altair EDEM: No materials specified for breakage warning using Tavares UFRJ breakage model

Rob Dekker

Good day,

Whilst trying to use the Tavares UFRJ Breakage model, I receive a warning that no materials are specified for breakage. This seems strange, since I defined a bulk material including all necessary properties (i.e. density, Poisson ratioc, shear modules, etc.) and let EDEM auto calulcute the mass. Once I start the simulation, I receive the following message: ''WARNING : Breakage : No materials specified for breakage''. Can anyone help me out where I should define the material for breakage (in my case BulkMaterial 1)?

Thanks a lot in advance!

Hi Rob,

Looks like you have not created dummy material where after particle breakage smaller particles will be moved to dummy material.

Please follow the instructions in the below tutorial but the tutorial is an APi based. However, the steps are same.

Also, you can go through the below webinar for more understanding of Breakage model.
