5. Create an acoustic SOL 108 Direct Frequency Response solution

Now that you have created transient blade forces, you will create a solution and acoustic load.

  1. In the Simulation Navigator, right-click your Simulation file, and choose New Solution.

  2. In the Solution dialog box, set the Analysis Type to Acoustic, and the Solution Type to SOL 108 Direct Frequency Response.

  3. On the Bulk Data tab, select the Enable Adaptive Order for Acoustic Elements check box .

  4. Click OK to close the Solution dialog box

  5. Click OK to close the Solution Step dialog box.

Next step
6. Create a Fan Noise load or loads
