An analysis mesh generation method is used for a modeling simulation of an article modeled according to a tool path. The method comprises: inputting the tool path for a product to be analyzed; defining an initial mesh that is made up of a number of microelements and encompasses the tool path; and determining overlap between the tool path and the microelements, removing non-overlapping microelements from the initial mesh, and storing an association of the tool path with overlapping microelements.
