Coupling Options

  Hello,
  I recently started working with Coupling between Fluent and Structural and in the past I was working with Coupling of Fluent with Rocky. I was wondering if there is a way to couple 3 systems together CFD-FSI-DEM by coupling Fluent-Rocky-Structural not in a one way manner.
  
  Thank you

  Not at present. Rocky can't cope with the deformed geometry in the current coupling systems. Moving geometry is fine, but we can't change it's shape.

  It is possible. you have to write macro for Ansys structure, rocky and fluent and main code to control these three software. with code you can deform your shape in rocky dem based on stress and deform output from FEA solver.

    Hello,
    Thank you for your reply. Is there any tutorial or course that could help me learn how to do such thing? If not do you have any tips?
    Best regards

      Because it is different from case to case, there is no straight forward procedure.
      explain your case.
