PROBLEM TO BE SOLVED: To provide a method of pre-treating a composite finite, a method of analyzing a composite material, an analysis service system, and a computer readable recording medium, which are easy to use for beginners or a veterans even if the analysis target material is a composite material.SOLUTION: The pre-treatment method for a composite fine element includes a unit skeleton element generation step of dividing an analysis region into structural lattices and/or unit skeleton elements of a non-structural lattice, a base material element generation step of generating a single or a plurality of base material elements so as to form the unit skeleton element, and a second-phase material element generation step of generating a single or a plurality of second-phase material elements having a plurality of nodes belonging to the unit skeleton element as angular nodes. The method designates a geometric pattern with a volume fraction, a size and a shape which relate to the base material element and the second phase material element of the unit skeleton element and arranging the second-phase material element of any unit skeleton element, and converts the unit skeleton element into the composite finite element by generating the second-phase material element based on the designation while arranging the second-phase material elements in a desired direction.SELECTED DRAWING: Figure 1 【課題】解析対象の材料が複合材料であっても初心者にもベテランにも使い易い、複合有限要素のプリ処理方法、複合材料の解析方法、解析サービスシステムおよびコンピュータ読み取り可能な記録媒体を提供する。【解決手段】解析領域を構造格子および／または非構造格子の単位骨格要素に分割する単位骨格要素生成工程と、該単位骨格要素を形成するように単数または複数の母材要素を生成する母材要素生成工程と、該単位骨格要素に属する複数の節点を角節点とする単数または複数の第二相材要素を生成する第二相材要素生成工程からなる複合有限要素のプリ処理方法であって、任意の該単位骨格要素の該母材要素と該第二相材要素に関する体積分率および寸法と形状の幾何パターンを指定するとともに、該第二相材要素を所望の方向に配置しながら、該母材要素および該第二相材要素を指定に基づき生成することにより、該単位骨格要素を該複合有限要素に変換する。【選択図】図１
