Patent ID: 6895354

Claim:
A thermal network data generating system for generating thermal network data for use in thermal analysis targeted at a coupling structure of a plurality of components, said system comprising: an input data processing section for selecting either a process regarding an analysis target as a two-dimensional structure or a process regarding the analysis target as a three-dimensional structure based on an analysis condition, and determining a component on which an area division is to be performed based on a component type; an area dividing section for performing one of dividing processes including quadtree area division regarding the analysis target as a two-dimensional structure and octtree area division regarding the analysis target as a three-dimensional structure, iterating said dividing process until each area divided by said dividing process contains only a single node having a position defined by constraint of components to be coupled, providing a node at a predetermined position of each area divided by said dividing process, and considering, among nodes having positions defined by the constraint of said components to be coupled, one of the nodes lying in a vicinity of nodes positioned at the predetermined positions of the areas divided by said dividing process as lying approximately in the same positions as those of the nodes positioned at the predetermined positions of the areas based on an index set arbitrarily; and a thermal network data generating section for generating thermal network data for connecting together determined nodes via thermal resistances having thermal resistance values according to the sizes and properties of said components to be coupled.
