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: /batch,list /com, Harmonic Analysis /PREP7 /TITLE, A volume inside cube ANTYPE,HARM 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 XDIV=29 ! Number of divisions along x-axis 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 LEN=27 HGT=20 RAD=0.9 !
