METHOD FOR INCREASING VELOCITY IN CALCULATING NUMERICAL INTEGRATION OF TWO-DIMENSIONAL BOUNDARY ELEMENT INTERPRETATION

摘要

PURPOSE: A method for increasing a velocity in calculating a numerical integration of a two-dimensional boundary element interpretation is provided to calculate a static electricity power of a structure rapidly by appending a distance calculating algorithm between nodes and to verify a result value effectively by comparing data values therewith. CONSTITUTION: Coordinate values of each node of a structure to be interpreted are received from a user(101). A boundary condition which decides whether a potential value of the structure is calculated or a flux density thereof is calculated is inputted according to each node(102). A rxi, and ryi values related to a node and a Gauss point are stored as a library function(103). A real distance value is substituted for a formulation of a boundary element method, and a numerical integration is calculated(104). A free term is calculated(105) and a boundary condition is applied(106), and thus an unknown value is searched(107).
