Abstract
Abstract A computer aided engineering (CAE) system for effecting heat analysis of electronic equipment or similar equipment by using a finite difference method, node method, etc. As the operator enters data representative of the tridimensional configuration of equipment, a dividing section divides the data into a plurality of blocks and generate node data representative of the individual blocks. A ventilation circuit generator and a heat circuit generator generate, respectively, a ventilation circuit network and a heat circuit network, or analysis models, by using the node data and data fetched from a data base. A processing section processes the ventilation and heat circuit networks to calculate temperatures and pressures. A tridimensional wire frame generator generates tridimensional wire frame data by processing parameter data indicative of the dimensions and kinds of structural parts and elements of the euqipment.
