> think you are actually solving a different problem. The PDE class is suitable for pure boundary value problems. However, the wave equation poses an initial value + boundary value...

> Here is an example of wave equation: https://github.com/lululxvi/deepxde/blob/master/examples/pinn_forward/wave_1d.py In this example, I have a couple of questions: 1. The L2 relative error is used as a loss term, correct?...

Can you add me to the slack channel, please?

How to merge the results of NN_U and NN_L together? Thanks for the great question @979736316, if it worked for you, please share the code. I’m trying to improve my...

I haven't found an example similar to what I'm trying to do. I'm trying to model the 2D-space 1D-time wave equation as follows f(x,5,t)=f(0,y,t)=f(5,y,t)=f(x,0,t)=0, where all the boundries are absorbing...

> @engsbk You try to model a point source? If so, this is not a problem of implementation in DeepXDE, instead, it is a problem of the current PINN method....

Is there any update on this issue? I want to know if the results improved when using hard constraints for BC. I'm having the same problem, and I did not...

This may be a naive question, but I've been using DeepXDE since it was based on TensorFlow, and I want to try running it with Pytorch, do I have to...

I tried to run this example of hard constraints: ``` ################################################################ ########################HARD IC & BC############################ ################################################################ def output_transform(x, u): x_in = x[:, 0:1] t_in = x[:, 1:2] freq = 1...

What would you suggest to implement: u(0,t) = sin(4 pi f t), and u(1,t) = 0, u(x,0) = 0 using hard constraints?
