A numerical analysis data creating method creates numerical analysis data that are obtained by analyzing an analyzing target. The method judges whether or not to create the numerical analysis data of the analyzing target using data that have been stored in a database part, searches the database part based on information related to the analyzing target and displaying a search result if the numerical analysis data of the analyzing target are to be created using the stored data, and creates and stores in the database part the numerical analysis data of the analyzing target by modifying usable data if necessary, when the usable data exist in the search result. The data that have been stored in the database part include numerical analysis data, analysis model data, material characteristic data and attribute data with respect to targets that have been analyzed.

A connector includes a contact pin in which a free end projecting from a supporting member comes into contact with an electrode of a first object and a second object, and a bending part is provided onto a base end such that the connector has an inclination against the first object and the second object. The rigidity of the bending parts is selectively set to be high by selectively increasing a thickness of the bending part.

When reliability evaluation of the whole electronic package is performed, the time required for simulation is decreased, while solder connection parts, in particular, are accurately analyzed. The whole analysis model creating unit creates a solder connection part model which has the same volume, height, and connection area as the volume, height, and connection area of the solder connection part. By means of dividing the solder connection model into multiple meshes, the first mesh data for use in electronic package analysis is created.

According to the present invention, a plurality of data items are displayed in different display forms corresponding to attributes of the data items in a list by recording a computer-readable recording medium with a data item list display program for causing a computer to display the data items in the different display forms in the list, the display forms corresponding to the respective attributes of the data items. Therefore, a data item can be displayed in the same display format in a list of data items of different attributes and in a list of data items of a single attribute, thus allowing users to easily understand the lists without confusion.

Data item list display apparatus, data item list display method, and computer-readable recording medium recorded with data item list display program

A tree structure diagram is displayed with icons which indicate functions of corresponding windows. The tree structure diagram represents a hierarchical relation between windows used in a multi-window system. An icon is added to each window to be arranged in a tree structure. The icon has an image indicating a function of the respective one of windows. The tree structure diagram is displayed together with the icon added to each window.
