the Subdivison property

I think it needs a bit extra explainment . In most cases you can let it on the default value or lower it to 1 , only for special cases you need 16 or variable , such a specialcase is the chain example . And be sure that you don't use the variable setting in conjuction with the Tugboat (or other high patch count models) and Fluidsurfaces , the simulation crash than because of too high polygoncount .

collision hull	setting for the propertie	remarks
	nothing , thats the original model :-)	860 patches
	1	1024 vertexes time for creating the collision hull 0.125 seconds
	4	3749 vertexes time for creating the collision hull 0.172 seconds
	16	14359 vertexes time for creating the collision hull 0.546 seconds
	Variable	97575 vertexes time for creating the collision hull 36.344 seconds (!)

What you see is, that the hull is in general the same (also the volume) (look also in this Projectfile) , only the resolution is higher , but the time and the vertexcount will growth when you use higher settings .
