A problem in valve analysis
 

There is a case for valve analysis .the detail conditions are as follows: (1)spool is tetra mesh and valve sleeve is hexa mesh. (2)spool move 3 mm relatively to sleeve at a speed of 1 mm/s (3)using moving mesh in analysis

I have some puzzles about this case: (1) shall I use ASI method ? (2) can spool be moved by "case.cgrd" through the event step ? (3) shall I couple the spool and sleeve in the events

appendix: spool(»¬·§·§Ð¾) sleeve(·§Ì×)

I especially want to know (3) : shall I couple the spool and sleeve in the events when using ASI method
