It would be really great if ne1 can help me out in using

1)Acoustic Mesh Cavity Panel

I just created a Rectangular box(using sheet metal) and imported in Hypermesh.

Tried meshing it from the Acoustic Mesh panel(In structures->selected box and adjusted the Mesh size-> Clicked on preview but it was giving an error.(No Component selected).

If I first surface mesh the box and follow the same procedure it is getting selected and working properly.(Generating two new components

1)Structural part(Volume Mesh)

2)Faces(Skin)

I deleted the box tried following the same steps as in tutorial to do a basic Modal Analysis to find the Acoustic Modes but I was getting an error saying

' *** ERROR # 1237 ***

CTETRA element number 657 references

a missing or invalid property number 2.'

Property number 2 is mat10_solids as in half car Model tutorial.

I am also attaching the Box which I created(It would be great if u can mesh it and tell me the procedure).

Here is the link
