Apparatus and method for performing finite element computation

An apparatus for performing finite element computation, comprising:

• a storage device;
• and
• a processor configured to perform a procedure including:
• obtaining a first dataset including first values calculated for a model that includes a plurality of nodes and a plurality of elements each being a region whose boundaries are defined by three or more of the nodes, the first values corresponding respectively to the plurality of nodes or elements;
• calculating a plurality of grid points addressed by coordinates of two or more orthogonal axes;
• calculating second values corresponding respectively to a subset of the grid points, based on positions of the nodes or elements and the first values included in the first dataset;
• storing a second dataset including the second values into the storage device;
• and
• restoring, when the second dataset is read out of the storage device, the first values corresponding respectively 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.
