    • A system for automatically dividing the form of an object to be analyzed using a finite element method, etc., into meshes, includes initial group generation means for generating a plurality of area division forms based on the form of the analysis object input through input means, and area division form evaluation means the generated area division forms. If the evaluation result does not satisfy a predetermined determination criterion, end determination means starts selection and crossover means for generating a new group and further starts mutation means for deforming the area division forms of the new group, then again starts the area division form evaluation means. If the evaluation result satisfies the predetermined determination criterion, an optimum area division form in the group is adopted as the optimum area division form. Division-into-meshes means subdivides the optimum area division form into meshes. The result of subdividing into the meshes is output to mesh output means. A method for automatically dividing the form of an object to be analyzed using a finite element method is also disclosed.
    • 一种用于使用有限元方法等将要分析的对象的形式自动划分为网格的系统包括:初始组生成装置,用于基于通过输入装置输入的分析对象的形式生成多个区域划分形式 ,区域划分形式评估是指生成区域划分形式。 如果评价结果不满足规定的判定基准,则结束判定单元开始生成新组的选择和交叉单元,进一步开始使新组的区域分割形式变形的变形单元,再次开始区域划分形式评价单元 。 如果评价结果满足规定的判定基准,则采用该组中的最佳区域划分形式作为最佳区域划分形式。 分割网格意味着将最佳区域划分形式细分为网格。 细分为网格的结果输出到网格输出装置。 还公开了一种使用有限元法自动分割待分析对象的形式的方法。
