Why does my small modal analysis run slower in ANSYS 11.0? Here are some solution times for a SOLID185 model:
54K 248/262
63K 310/324
73K 395/420 (esize,.00550)
85K 503/2439! (esize,.00525)
89K 485/1222 (esize,.00500) 10.0 times for this model are 546/602)

This was due to a change in the way I/O is done, which was not efficient for this model size. The problem is corrected in 11.0 SP1. (ref: defect 59253) Development provided a workaround: Set WIN_BUFFER=1. |
