An improved system and method of creating an initial configuration of a finite element mesh model of a blank sheet metal used in a computer simulation of sheet metal forming process is disclosed. According to one aspect of the present invention, the finite element mesh model of the blank is initially configured as a flat plate without any weight before performing the gravity loading phase of the simulation. A user-specified initial imperfection is then applied to the initial flat plate model so that a desired bent shape occurs predictably.
