Defining incident waves

You can model incident wave loading due to external acoustic wave sources. Select InteractionCreate from the main menu bar, and select the source point, the standoff point (for all incident wave loading definitions except for those using the CONWEP model), and the surface. When specifying source points and standoff points, you can select only reference points that are not associated with any other model component. You can create incident wave interactions in the following types of analyses: implicit dynamic, explicit dynamic, direct steady-state dynamic, and subspace-based steady-state dynamic. Incident wave interactions are active only in the steps in which they are created and do not propagate to any of the following steps. If your model includes incident wave interactions, you must edit the model attributes (see below) to specify an acoustic wave formulation for the model.
