Crash When Enabling Particle Breakage in Rocky-Fluent Coupling

      Hello,

      I attempted to couple Rocky 2024 R2 with Fluent 2024 R2 using the following steps:

      Through the Rocky interface, I selected Help -> Tutorial Workshops -> 14.Tutorial - Fluidized Bed -> Downloaded the dem_tut14_files.zip file from
      section 14.1.5.

      Then, from Rocky interface, File -> Open project -> selected the file tutorial_14_B_pre-processing-restart.rocky in dem_tut14_files\dem_tut14_files\tutorial_14_B_pre-processing\

      Then in the Data panel in the Rocky interface, I clicked on solver and then from the Data Editors panel I clicked on start. This opened Fluent automatically and the simulation started successfully, coupling Rocky and Fluent 2024 R2.

      I then modified the test case by changing the particle shape to polyhedral and enabling breakage for the particles. However, when I run the simulation with breakage activated, the Rocky interface closes and the software crashes. Simulations without breakage run without issues, so the problem appears to be related specifically to breakage.

      Could you please advise how to resolve this issue in order to simulate wet grinding?
