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

Rob Dekker

Hello everyone,

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 ratio, 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,

You also need to define the breakage model parameters in the physics section:

You can take a look at this tutorial for further details:
