【Abstract】 Based on analyzing characteristic of heat exchange with finite element method, the paper transforms the finite element computing problem into a nonlinear optimizing one with some restriction, and solves it using the Hopfield neural network. The result to simulate a simple temperature field with the method shows that the neural network can be applied to finite element model’s resolving.更多还原
