Abstract: A method, apparatus and computer readable medium for performing a computer simulation a physical object, includes receiving at least one selection by a user with respect to usage of a simpler model or a more complex model to be used to model at least one attribute of the physical object; performing a computer simulation of the physical object based on the at least one selection received from the user; and rerunning the computer simulation a plurality of times using results obtained from earlier run computer simulations, to obtain an accurate representation of the physical object.
