This calculation method is characterized by comprising: a first step in which structural analysis is performed under a first heating condition including a first heating line, and a first trial in which the analysis result is compared with a target shape is repeated; a second step of selecting, as a first selected heating line, a first heating line set in a first trial in which an analysis result in the repeated first trial is close to a target shape; a third step of performing structural analysis under a second heating condition including the first selected heating line and the second heating line, and repeating a second trial of comparing the analysis result with the target shape; and a fourth step of selecting, as a second selected heating line, a second heating line set in a second trial in which the analysis result in the repeated second trial is close to the target shape; in the first or third step, the analysis result and the target shape are divided into a plurality of blocks, and the analysis result a
