    Hello Brian, 

    When exporting your model, can you please use the option "Merge" under Include Files:

    If it still does not work, please share the generated deck. 

    Thanks,

    Hi Vinicius,

    I want to ask why there is a difference between the new version and the old version when using acoustic cavity meshing.

    Thanks

    Hi Brian,

    Please share the include file too as the mistake looks to be in that file.

    Thanks

    Hi Rajashri,

    The community doesn't allow to sharing of the included file. But I fixed this based on Vinicius's answer.

    Thanks
