Reply To: ACT Acoustics Extension Status (Deprecated)?

[peteroznewman]

The functionality that was enabled by the old acoustic ACT extensions is no longer needed since most of the functionality is now included in the native Mechanical app. I am using Ansys Student 2024 R2 and I can select Harmonic Acoustics instead of Harmonic Response. Air is automatically included in the list of materials. In Mechanical, under Geometry, click on the solid body and assign Air to the solid cubic body.  

To get rid of the ? on the Analysis Settings, enter the Frequency Range Maximum.

Right click on Mesh to create a mesh. You should select an element size so that six quadratic elements will be created for one wavelength of the maximum frequency you requested.

Click on the Harmonic Acoustics branch of the Outine and on the Context Environment tab, you can see a drop down button for Acoustic Excitations, select Mass Source. I tried to assign a Mass Source to a node in a Named Selection, but it would not take that. It seems there are still some gaps in the functionality.  I was able to assign a Mass Source to a Vertex, so as a work around, I had to go and make a vertex in the cube geometry first.
