PROBLEM TO BE SOLVED: To shorten model creation time while maintaining analysis accuracy.SOLUTION: A boundary line 50 passing an upper side 58A of a bead shape line 58 is set as a boundary between a bead part 54 and a tire body part 56, and a mesh center 74 is set inside the bead shape line 58. On a lower side from the boundary line 50, a critical point 76 for representing a tire member shape line 64 is set, and also, a critical point 78 for representing the bead shape line 58 is set. With the critical points 76 and 78 being base points, toward a tire contour line 62, a mesh line 80 leading to the adjacent tire member shape line 64 is created, and the mesh line 80 is extended until it reaches the tire contour line 62. Also, with the critical points 76 and 78 being the base points, toward the mesh center 74, the mesh line 80 leading to the adjacent tire member shape line 64 or the bead shape line 58 is created, and the mesh line 80 is extended until it reaches the mesh center 74. |
