1. A method for determining absorbent article effectiveness of a virtual absorbent article, said method comprising the steps of: providing a virtual body model; providing a virtual absorbent article model; providing virtual simulation software; running a virtual simulation of deformation of said virtual absorbent article model in proximity with said virtual body model; running a virtual simulation of the fluid balance of said virtual absorbent article model in proximity with said virtual body model; coupling said virtual simulation of deformation of said virtual absorbent article model and said virtual simulation of the fluid balance of said virtual absorbent article model; and determining absorbent article effectiveness of said virtual absorbent article model in proximity with said virtual body model.
