PDE

Hi,

Very interesting work! I have one small question: taking the 2D Burger's equation as an example, if the viscosity value is changed, we need to retrain the neural network?

Best wishes

Hi - yes, we need retrain the network. If the viscosity value is changed, the governing equation will be different for the trained model. But here you may try retraining the network of a different viscosity model (e.g., 400) based on the current trained model (e.g., 200). It is also called curriculum learning. Hope that answer helps you.

Make sense. Thanks for your quick reply!
