It seems that a trained network can only be used to predict the results of the same geometry with the same boundary condition and initial condition. Once any of the above-mentioned conditions is changed, the network has to be trained again for new predictions. I am wondering is there a possibility to generalize the approach such that once the network is trained, it can be used for predictions with different initial and boundary conditions? Thank you!

Yes, PINN is for specific IC/BC. If you want to train a network for different IC/BC, you can use these IC/BC as an extra network input, and train the network for different IC/BC. Another way is to use DeepONet, see https://doi.org/10.1038/s42256-021-00302-5
Hi Lu,
Thank you for sharing the library.
