Setting Up the Morpher

Use the Morpher to allow the fluid mesh to deform in response to the imported nodal displacements from Abaqus.

Create a morphing motion and assign it to the fluid region:

Right-click the Tools > Motions node and select New > Morphing.
A new Morphing node is added under the Motions node.
Select the Motions > Morphing node, and set Morpher Method to RBF.
The RBF morpher automatically removes vertices on boundaries while the simulation runs. The Automatic Thin-out Cl factor determines the number of control vertices that are used in each iteration. As the level of deformation increases, the morpher automatically uses more control vertices.

Decrease the Automatic Thin-out Cl factor to increase the sensitivity of the morpher to the mesh deformation:

Select the Motions > Morphing > RBF Parameters node and set Automatic Thin-out Cl to 0.5.

To apply this motion to the fluid region:

Select the Regions > plateFluid > Physics Values > Motion Specification node and set Motion to Morphing.
The FSI boundary will be automatically set to move according to the displacements imported from Abaqus, once that a co-simulation link is set up. See Specifying Co-Simulation Settings.

Change the morpher method for the inlet and outlet boundaries to Fixed Plane. This morpher method is suitable for the selected boundaries and is more computationally efficient:

Expand the Boundaries node.
Multi-select the Inlet and Outlet nodes.
Right-click one of the selected boundaries and select Edit.
Select the Physics Conditions > Morpher Specification node and set Specification to Constraint.
Select the Morpher Constraint Specification node and set Constraint to Fixed Boundary Plane.
Close the Multiple Objects dialog.

To prevent inaccuracies from accumulating during the simulation (due to interpolation), change the mesh morpher settings:

Select the Solvers > Mesh Morpher node and activate Morph From Zero.
