9.6.3.6. Define Contact for Fluid Structure Interfaces

Note the following requirements and considerations for contact defined at a Fluid Structure Interface (FSI):

  • The contact side must be on the acoustic body and the target must be on the structural body.

  • Supports the Bonded, Pure Penalty, and MPC formulations.

  • The Pure Penalty formulation is not supported for contact conditions between two acoustic bodies.

  • The Nodal - Dual Shape Function Projection (keyo,cid,4,4) option, of the Detection Method property, is used by default for FSI contact defined using the Pure Penalty formulation.

  • The Combined option (KEYOPT,cid,4,5), of the Detection Method property, is not supported for the MPC formulation.
