Hello,

I am modeling a set of tubes for an Eigenfrequency study. Within the Pressure Acoustics Frequency Domain node, I let Comsol apply the automatic Sound Hard Boundary condition to all walls. I then applied a Sound Soft Boundary to the outlet face.

Does this correctly simulate a tube with a closed inlet boundary and open exit end? I have found very little in the documentation covering what I hope are straightforward settings.

Thanks,
Thomas
