Abstract A new prediction method using the combination of the two-dimensional Discrete Cosine Transform and the Maximum Entropy method has recently appeared to estimate the dynamic changes of metallographic structures of the single crystal Nickel-based superalloy for gas turbine blades during the high temperature creep deformation. In the analysis of this method, simple geometrical models are used to estimate the dynamic changes of the phase transition. However, it has not been understood how the difference between the multiple simple geometrical models affect the result of the prediction of dynamic changes of structures yet. Therefore, three different simple geometrical models meshed into 21 × 21 (441 pixels) are prepared as the target model and demonstrated via the above mentioned new method, in the situation that the starting simple geometrical model is the same one. The first model is a symmetrical model whose symmetrical plane is parallel to the i axis and perpendicular to the j axis at the 10th scale line, the second one is a model which the first model is moved in the j axis direction by one pixel and the third one is a model which the first model is moved in the j axis direction by two pixels. As a result, the dynamic changes obtained from the symmetrical model and the one pixel deviation model are the most realistic of the three models.
