CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application is a continuation under 35 U.S.C. 120 and claims priority to U.S. application Ser. No. 10/641,007, filed Aug. 15, 2003 and incorporated by reference herein. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention generally relates to programs for causing a computer to execute a method of generating mesh data and apparatuses for generating mesh data, and more particularly to a program for causing a computer to execute a mesh data generating method capable of relatively simply generating highly accurate mesh data and a mesh data generating apparatus suitable for such a method. [0004] 2. Description of the Related Art [0005] Herein, mesh data refers to data that is obtained by dividing a predetermined structure into a mesh of elements, obtaining a characteristic value representing the characteristics of each mesh element, and approximating the structure by the set of the mesh elements in the case of performing analyses using a computer, such as a structural analysis, a heat transfer analysis, a fluid analysis, a thermal fluid analysis, and an electromagnetic field analysis, so that such analyses are effectively performed. [0006] In recent years, as electronic devices have been reduced in size and weight as peripheral devices for computers, it has been required to design the structure of the electronic devices, especially, printers, so that the behavior of heat generated therefrom is suitably controlled. For this purpose, it is necessary to analyze the behavior of heat in the complicated internal structures of the electronic devices with good accuracy. Thermal fluid analysis is a technology for achieving such accurate analysis, and mesh data is employed as data to be provided to a tool for performing the analysis by a computer, that is, software. [0007] Japanese Laid-Open Patent Application No. 11-025293 discloses a method for generating the mesh data. This method, taking advantage of the merits of the orthogonal difference method and the finite element method, has an object of enabling an analysis model having a complicated shape, where an object of analysis is formed of a plurality of substances or regions, to be divided easily into a mesh of elements with good accuracy. [0008] Japanese Laid-Open Patent Application No. 11-025292 discloses an automatic mesh dividing method which, in an analysis using the finite element method, is capable of generating mesh data of a mesh size satisfying required analysis accuracy and of using an equivalent mesh, an inequivalent mesh, or a junction mesh as required. [0009] Further, Japanese Laid-Open Patent Application No. 9-185729 discloses an orthogonal difference mesh data creating method having an object of easily creating orthogonal difference mesh three-dimensional model data required for analysis by a CAE (computer aided engineering) system from three-dimensional stereoscopic model data created by a CAD (computer aided design) system. SUMMARY OF THE INVENTION [0010] However, these methods, which are intended basically for a complicated curved-surface structure, have relatively complicated operation algorithms. As a result, these methods are considered to require a considerable amount of processing and time in operation for an electronic device having a relatively simple structure so as to be regarded as a set of rectangular shapes. [0011] Accordingly, it is a general object of the present invention to provide a method of dividing an object of analysis into a mesh of elements in which the above-described disadvantage is eliminated. [0012] A more specific object of the present invention is to provide a method of effectively dividing an object of analysis into a mesh of elements with good accuracy with a relatively simple structure. [0013] The above objects of the present invention are achieved by a method of generating mesh data by orthogonally dividing a target object into a mesh of elements by a plurality of grid lines orthogonally crossing each other, the method including the steps of (a) detecting vertexes of the target object, and (b) dividing the target object orthogonally by the grid lines passing through the detected vertexes. [0014] The above objects of the present invention are also achieved by a program for causing a computer to execute a method of generating mesh data by orthogonally dividing a target object into a mesh of elements by a plurality of grid lines orthogonally crossing each other, the method including the steps of (a) detecting vertexes of the target object, and (b) dividing the target object orthogonally by the grid lines passing through the detected vertexes. [0015] The above objects of the present invention are also achieved by a computer-readable recording medium storing a program for causing a computer to execute a method of generating mesh data by orthogonally dividing a target object into a mesh of elements by a plurality of grid lines orthogonally crossing each other, the method including the steps of (a) detecting vertexes of the target object, and (b) dividing the target object orthogonally by the grid lines passing through the detected vertexes. [0016] The above objects of the present invention are further achieved by an apparatus for generating mesh data by orthogonally dividing a target object into a mesh of elements by a plurality of grid lines orthogonally crossing each other, the apparatus including a detection part detecting vertexes of the target object, and a division part dividing the target object orthogonally by the grid lines passing through the detected vertexes. [0017] According to the present invention, mesh data to be input to the thermal fluid analysis tool of an electronic device can be generated with relative ease. Further, with a relatively simple configuration, the original CAD data of the electronic device can be converted to orthogonally divided mesh data formed of a minimum required number of mesh elements while maintaining the original structural information as much as possible. As a result, in the case of causing a computer to execute the method of the present invention, the amount of processing and time required in analysis operations can be effectively reduced, so that the thermal fluid analysis of the electronic device can be performed far more efficiently.
