To calculate properties of a high polymer material including a first polymer and a second polymer which are mutually insoluble.SOLUTION: There is provided a simulation method for a high polymer material model. This method includes a process S11 of inputting a high polymer material model including a first polymer model and a second polymer model as a mutual separation structure. Further, a computer executes: a first process S1 of calculating a first concentration distribution of the first polymer model and second polymer model; a second process S2 of virtually sectioning the high polymer material model into a plurality of regions; a third process S3 of calculating a second concentration distribution of the first polymer model and second polymer model in the plurality of regions, respectively; a fourth process S4 of calculating properties of at least one region among the plurality of regions based upon the second concentration distribution; and a fifth process S5 of calculating properties of the whole system of the high polymer material from the properties of the at least one region among the plurality of regions.SELECTED DRAWING: Figure 2 【課題】 互いに非相溶性の第１ポリマー及び第２ポリマーを含む高分子材料の物性を計算することが可能となる。【解決手段】 高分子材料モデルのシミュレーション方法である。この方法は、第１ポリマーモデル及び第２ポリマーモデルを相分離構造として含む高分子材料モデルを入力する工程Ｓ１１を含む。さらに、コンピュータが、第１ポリマーモデル及び第２ポリマーモデルの第１濃度分布を計算する第１工程Ｓ１と、高分子材料モデルを複数の領域に仮想区分する第２工程Ｓ２と、複数の領域それぞれの第１ポリマーモデル及び第２ポリマーモデルの第２濃度分布を計算する第３工程Ｓ３と、第２濃度分布に基づいて、複数の領域のうち少なくとも１つの領域の物性を計算する第４工程Ｓ４と、複数の領域のうち少なくとも１つの領域の物性から、高分子材料の系全体の物性を計算する第５工程Ｓ５とを実行する。【選択図】図２
