A method, device, and system are provided for the efficient transfer of snapshot data during a snapshot delete action. In accordance with the method, a metal layer is deposited into the micro-structures with a process, such as an electroplating process, that generates metal grains that are sufficiently small so as to substantially fill the recessed micro-structures. The parent virtual machine is temporarily or permanently suspended. When used in a lithography process, the composition ensures an effective sensitivity, makes more uniform the distribution and diffusion of the acid generating component in a resist film, and suppresses deactivation of acid at the substrate interface. Further aspects relate to a stretching function presented as one Look Up Table, thus allowing fast computations on limited computing devices such as consumer electronic devices. A force update vector is calculated for a given cell instance within the region A where neighboring cell instances have an exponentially larger grid size as cell instances extend further away from the given cell instance.
