NUMERICAL ANALYSIS DEVICE, NUMERICAL ANALYSIS METHOD, NUMERICAL ANALYSIS PROGRAM

摘要

To provide a numerical analysis device, a numerical analysis method, and a numerical analysis program capable of maintaining and improving analysis accuracy of a point source model regardless of a method of element division.SOLUTION: A device for numerically analyzing a physical phenomenon by a finite element method comprises: analysis means which divides an analysis area around a point source part modeled by a node string into a finite number of elements to numerically analyze physical amount of the analysis area by using the finite element method; correction means which corrects physical properties of a predetermined element around the point source part; and calculation means which, based on the physical amount obtained by numerically analyzing by the analysis means by using the physical properties corrected by the correction means and the physical properties before correcting by the correction means, calculates another physical amount.SELECTED DRAWING: Figure 1
