SIMULATION METHOD FOR MODIFIABLE SIMULATION MODEL

A simulation method includes a step of modifying a model in a simulation process, a step of detecting elements influenced by the model modification, and a step of performing a resimulation process while returning to the earliest one of the influenced elements. According to the disclosed method, a resimulation process associated with the model modificaiton can be realized in a short time without the inconvenience of the prior art in which the resimulation is carried out with a waste of time even for elements which are not influenced by the model modification or elements which need not to be subjected to the resimulation.
