Default Ansys hang subtracting volumes

Aco1000 is on a distinguished road
Hi all,

Program 1 below is program which creates two volumes and while subtracting them the ansys hangs and constantly allocates more memory.

Program 2 is a similar one but with a simpler inner volume which completes successfully.

Ansys version 12.0.1 running on win xp sp2. The program is run on Mechanical APDL. The program is somehow derived from ANSYS room acoustic example.

I would appreciate any help.

Thanks

Program 1:

ET,1,30 ! Acoustic elements in contact with walls and vibrating surface
ET,2,30,,1 ! Acoustic elements in interior (not in contact with walls)

! Set parameters for mesh generation

YDIV=19 ! Number of divisions along y-axis
ZDIV=1 ! Number of divisions along z-axis
CDIV=2 ! Number of divisions along radius

! Dimensions of the room
