  Hi, I am planning to do a study in Ansys Rocky about a tool that examines the structural damping behavior of particles in a limited volume at certain constant frequency excitations. Does anyone have information about the feasibility of this study with Rocky & Ansys co-simulation and the document I can benefit from? I can share more details if you request.

  You can find some documents that might benefit you from the following links:
  /forum/forums/topic/rocky-dem-frequency-dependent-damping/ suika game, which provides the basic information on how to use Ansys Rocky, including the installation, the user interface, the workflow, and the examples.
  /courses/wp-content/uploads/sites/2/2021/01/Lesson4-Applications_of_Structural_Instabilities.pdf , which provide step-by-step instructions on how to perform various simulations with Ansys Rocky, including co-simulation with Ansys Mechanical and Ansys Fluent.

    Hi, thank you for your help, but I could not reach the documents you mentioned in the links you gave, could there be a problem?

  Hello Can,
  this study can be simulated by coupling Ansys Rocky (for the DEM side) with Ansys Mechanical (for FEA analysis). Some documents you can check to learn more about this coupling strategy are listed:
  - Rocky Tutorials 12 and 15
  - Rocky User Manual
  - FEA-DEM Webinar
  Furthermore, the geometry excitations can be modeled by using the Motion Frames tool in Rocky, which you can also check on how to setup in Rocky User Manual.
  
  Feel free to reach out and continue this conversation.
  
  Best regards,
