Boundary element analytic method and a boundary element analytic program

摘要

An object of the present invention is to provide a boundary element analytic method and a boundary element analytic program, which are capable of coping with the problem of diversity in symmetric property to be encountered when carrying out an analytic operation by taking advantage of the symmetric property of a subject to be analyzed, and thus providing an efficient analysis. ;Various types of data for the use in the boundary element analysis, which have been previously input at step S101, are stored at step S102. To carry out this operation, at least boundary element definition information for defining a boundary element in the subject to be analyzed and state quantity information in which boundary element identification information for identifying the defined boundary element is associated with the boundary element for each state quantity thereof. At step 103, the input different types of data are used to generate a digitized boundary integral equation with a boundary value at a point of element on each defined boundary element taken as a variable. Then, at step S104, the generated boundary integral equation is assigned with the input boundary condition to sort out any unknowns, thus obtaining the simultaneous equations. The obtained simultaneous equations are then solved to determine respective values for the unknowns.
