A calculation method for physical value for calculating physical values in a numerical analysis method for numerically analyzing a physical phenomenon, comprises a physical value calculation step of calculating physical values in an analysis domain divided into a plurality of divided domains, wherein in the physical value calculation step, the physical values are calculated by using: a discretized governing equation that uses values not requiring coordinates (Vertex) of vertices of the divided domains and connectivity information (Connectivity) of the vertices and that is derived on the basis of a weighted residual method; and a calculation data model in which volumes of the divided domains and characteristic values of boundary surface indicating characteristics of boundary surfaces of adjacent ones of the divided domains are provided as the values not requiring coordinates (Vertex) of vertices of the divided domains and connectivity information (Connectivity) of the vertices.

A method for storing time series data comprising storing short period data at an arbitrary sampling period and storing long period data at a sampling period longer than the arbitrary sampling period, in which the time series data are stored in a hierarchically correlated manner. Even when a great amount of data are stored, processes such as reading out, transferring, and displaying requisite data can be efficiently executed at high speed.

A direct current magnetic field is applied to a molten metal bath to control the movement of molten metal. A glass ribbon is formed on the molten metal bath to have a predetermined thickness and is moved on the surface of the molten metal bath controlled by the magnetic field, during which the glass ribbon is cooled.

Method for manufacturing float glass

Difference in height is provided between a first surface of a molten metal bath at the upstream side in a vessel and a second surface thereof by means of a linear induction motor. A glass ribbon supplied to the first surface is formed to have a predetermined thickness while it is moved from the first surface to the second surface.
