WebHeat transfer takes place in 1 of the three ways namely: Conduction, Convection and Radiation We will discuss each of these methods in detail. Conduction. Conduction is the method of transfer of heat within a body or from one body to the other due to the transfer of heat by molecules vibrating at their mean positions. WebTemperature or heat flux boundary conditions may be specified at any point within the finite element system. Mathematically, it can be shown that the method converges to the exact solution as the number of elements is increased; there- fore, any desired degree of accuracy may be ob- tained. michael g barnes facebook
