Create and Edit a Semi Infinite Fluid (SIF)

An acoustic element represents the infinite propagation medium for an exterior radiation scenario/problem. It can be attached to multiple acoustic subsystems to transfer the energy. The acoustic connections automatically consider the propagating surface area for connections. This element automatically creates semi-infinite acoustic space and connects the exterior-most acoustic space that you select.

  1. From the Model ribbon, click the Acoustic > SIF tool.


    Figure 1.
  2. Create SIF.
    1. From the Entity selector, click an Acoustic space subsystem, which needs to be connected to a SIF.
    2. Click Create.


      Figure 2.
  3. A Semi-infinite Acoustic Space 3D element is created with connecting acoustic space subsystems, which are selected in the previous step using the acoustic connections.
  4. The exterior surface of the acoustic space is considered for the acoustic connection's area.
  5. Right-click SIF to edit the subsystem and update the parameters.
