Activating the Morpher

Activate the mesh morpher to deform the fluid mesh according to the spindle ball displacements.

Simcenter STAR-CCM+ exports traction loads (pressure + wall shear stress) to the partner code, and the partner code solves for the solid surface displacements. In Simcenter STAR-CCM+, the displacements are used as inputs to the mesh morpher.

To activate the mesh morpher:

Expand the Tools node.
Right-click the Motions node and select New > Morphing.
Select the Morphing node and set Morpher Method to RBF.

Assign the morphing motion to the fluid region:

Expand the Regions > Spindle Valve Fluid > Physics Values node.
Select the Motion Specification node and set Motion to Morphing.

Select the appropriate morpher method for the relevant boundaries:

Expand the Spindle Valve Fluid > Boundaries > slidingwall > Physics Conditions node.
Select the Morpher Specification node and set Specification to Constraint.
Select the Morpher Constraint Specification node and set Constraint to Initial Boundary.
This setting makes sure that the ball only moves in the direction of the spindle axis.

At the periodic interfaces, you constrain the mesh vertices on the interface plane:

Multi-select the Boundaries > Periodic1, Periodic2, SpindleValve/SpindleValve[0], and SpindleValve/SpindleValve[1] nodes.
Right-click one of the selected boundaries and select Edit...

In the Multiple Objects edit dialog, set the following properties:


Node	Property	Setting
Morpher Specification	Specification	Constraint
Morpher Constraint Specification	Constraint	Boundary Plane
Morpher Plane Constraint Specification	Use Triangulated Plane	Activated

The spindleball boundary moves in response to the ball displacements imported from the partner simulation. Simcenter STAR-CCM+ automatically sets the morpher method for this boundary when you assign it to a zone for co-simulation.

As this co-simulation uses the implicit coupling scheme, instruct the morpher to update the fluid mesh at every inner iteration:

Select the Solvers > Mesh Morpher node and activate Morph At Inner Iterations.
