WebThe method was originally developed for engineering analysis to model and analyse complex systems in mechanical, civil, and aeronautical engineering. The basics of the method can be derived from Newton's laws of motion, conservation of mass and energy, and the laws of thermodynamics. FEM can be used, for example, to determine the structural ...
WebThe basic model for the diffusion of heat is uses the idea that heat spreads randomly in all directions at some rate. The heat equation is a deterministic (non-random), partial differential equation derived from this intuition by averaging over the very large number of par-ticles.
