| Abstract: | The integral equation,boundary integral equation and their discrete equations for transient heat conduction are developed by using time independent foundamental solutions and variable seperating methods.The domain integrals are converted to the equivalent boundary integrals and effective coordinate functions are offered.At last,a fortran program is designed for two and three dimentional element to solve a example successfully. |
