Finite element arithmetic program, finite element arithmetic device, and finite element arithmetic method

摘要

A model is defined as a collection of nodes and elements, where each element is a region whose boundaries are defined by three or more nodes. A processor obtains a first dataset including first values calculated for different nodes or elements of the model. The processor sets a plurality of grid points addressed by coordinates of two or more orthogonal axes, and calculates second values corresponding respectively to a subset of the grid points, based on positions of the nodes or elements and the first values. The processor then stores a second dataset including the second values into the storage device. When the second dataset is read out of the storage device, the processor restores the first values corresponding to the plurality of nodes or elements, based on positions of the subset of the grid points and the second values included in the second dataset.
