Abstract: The several typic transient temperature problems in the thermal design of a geostationary communication satellite are discussed in this paper. Stiff steady auto-integration is used to solve 250 nodes nonlinear differentiating equations. A good result has been obtained applying the technique of sparse matrix to corrected iteration procedure.
