We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

flow+fracturing simulations

  Rocky's SPH+DEM combination seems to be a powerful tool for fluid-structure interactions. Can it be used to solve the following problem?
  A thin layer of liquid sits on a rigid substrate, with one of its faces exposed to air. A brittle sphere impacts the substrate. As the sphere moves, it may touch the substrate and fracture while interacting with the liquid. Can Rocky's SPH+DEM coupling handle such a problem? The flow of air is unimportant, and the flow of liquid may be considered incompressible.
  Thank you very much!

  Hello Rui,
  this scenario can be simulated by SPH-DEM in Ansys Rocky with breakage enabled. You can check on Rocky Tutorial 25 to learn more about SPH-DEM setup, and on Rocky User Manual to get insights about particle breakage.
  Feel free to reach out and continue asking your questions here.
  
  Best regards,
  Lucas
