 In recent years, Physics-Informed Neural Networks[1] have been applied to various types of application tasks. 
 This example shows how to train a neural network to predict temperature distributions given new initial and boundary conditions. The neural network was trained using a loss function that includes a data loss component, which measures the discrepancy between the network's predictions and targets derived from finite element simulations, as well as a physics-informed loss component that evaluates the residual of the governing partial differential equation (PDE).

 The PDE used in the loss function is the transient heat equation:
