  Hello,
  I am trying to simulate wet grinding using Rocky 2024 R2, but I encountered the following error:
  Does this mean it is not possible to simulate a system with both liquid and particle breakage in Rocky?
  What are the available options for modeling such a system? If this is not currently supported in Rocky, would coupling Rocky with Fluent be a suitable approach to simulate wet grinding?

  Hello,
  
  It is not possible to simulate SPH with particles breakage. There's no limitation on simulating particles breakage with CFD Coupling. It depends on your application, but it might be a good option.

    Thank you very much for your response. I would try to couple Rocky with Fluent to simulate wet grinding.
