Anti-warping design method for resin molded article, recording medium, and anti-warping design device for resin molded article

An anti-warping design method for designing a resin molded article on a programmed computer, the method comprising:

• dividing a model of the molded article into a plurality of small elements each having nodes which are vertexes thereof;
• calculating sensitivity values for at least part of the elements with respect to warpage of the molded article;
• and
• displaying a distribution of the sensitivity values,
• the calculating of the sensitivity values including calculating, for each of the at least part of the elements, sensitivity of influence exerted on warpage at an evaluated position of the modeled article by shrinkage of the element, as the sensitivity value of the element, the sensitivity of influence being warpage amount of a predetermined node of a predetermined element at the evaluated position in a predetermined direction.
