To perform a thermal-fluid analysis and thermal-stress analysis in a short time by preparing a fluid analysis mesh and a structure analysis mesh, in parallel with each other, from the three-dimensional model of fluid machinery, automatically mapping the data of the results obtained by a thermal-fluid analysis based on the fluid analysis mesh according to the structure analysis mesh, and calculating a thermal-stress based on the structure analysis mesh.
In a development process mainly using a three-dimensional model data, a designer oneself prepares a three-dimensional model in a design operation (S1, S2). Both a fluid analysis and a structural analysis can remarkably reduce an operation time using an automatic tetra mesh. Namely, the fluid analysis mesh and structure analysis mesh are prepared by an automatic tetra mesh division dividing the mesh into tetrahedron cells (S3, S5). Thus, because both the fluid analysis mesh and structure analysis mesh are prepared automatically in parallel with each other, the generation of mesh by manual operation can be eliminated and, because mapping is performed automatically, the mapping by manual operation can be eliminated.
