meshing with ICEM
 

Hello,
For my bachelor thesis (about acoustic levitation) I have to simulate a three-axis acoustic levitation in ANSYS CFX. But I have a problem by meshing the model with ICEM. I know how I can make the meshing when the probation, which is levitated, is fixed. But in my simulation the probation is flexible and forces like the gravitation are acting on the probation. Because of this the probation can move to the ground. My task is now to simulate that the levitationforces suspends the gravitation. The meshing must be changed by the liability.
Can someone help me how I can make this flexible meshing?
