Define the Morphing Motion

Set up mesh morphing around the blade regions so the mesh updates based on the beam displacements imported from the external motion file.

  1. Expand the Regions node and multi-select the Blade 1, Blade 2, Blade 3, and Blade 4 regions.
  2. Right-click one of the selected regions and select Edit....
  3. In the Multiple Objects dialog expand Physics Values > Motion Specification and set Motion to Morphing.
  4. Click Close.
  5. Expand the Boundaries node for each blade region and multi-select all four Blade boundary nodes.
  6. Right-click one of the selected boundaries and select Edit....
  7. In the Multiple Objects dialog, set the following properties:
    Node Property Value
    Physics Conditions
    Morpher Specification Specification Displacement
    Morpher Displacement Specification Specification Total
    Physics Values
    Morpher Rigid Boundary Motion Rigid Motion Rotation
    Morpher Total Linear Displacement Method Field Function
    Vector Function Co-Simulations > Co-Simulation: Displacement
  8. Click Close.
  9. Expand the Boundaries node for each blade region and multi-select the Overset Cylinder, Overset Inner, and Overset Outer boundaries.


  10. Right-click one of the selected boundaries and select Edit...
  11. In the Multiple Objects dialog, expand Physics Conditions > Morpher Specification and set Specification to Floating.
    By setting the morpher specification to Floating, you define the morphing such that the overset boundaries move according to the interpolation of the displacement vector describing the blade boundaries morphing. Hence, the overset regions will morph along with rotation motion of the blades.
  12. Click Close.
  13. Expand the Interfaces node. For each Overset Mesh, expand the Physics Conditions node. Multi-select all four Overset Hole Cutting Options and enable Alternate Hole Cutting.
    The Alternate Hole Cutting approach is a more robust method when running on many cores.
  14. Multi-select all four of the external beam regions under the Regions node (Beam 1, Beam 2, Beam 3, and Beam 4).
  15. Right-click one of the selected regions and select Edit....
  16. Expand Physics Values > Motion Specification and make sure Motion is set to Rotation.
  17. Click Close and save the simulation.
