Hello Richard,

EVPARM PISTON 1000 34.5 115.0 0.0 COMP 69.0; *SET YP 1.5875 3.175; Piston in comp.; *LOOP 1 20 1; *SET YP 66.675 -3.175; Piston in exp.; *LOOP 1 20 1; My cell size is 3.175 cube and cyl. size is 82.55.

Now, pison comp. motion goes properly but when it comes to execute the first expantion stroke event it gives me error mess. that there are x active cells with zero vol. $ check your egrid commands. I dont see any thing wrong in .cgrd commands as it works fine for compression stroke.

I really appreciate your concern. Thanks alot.
