Hello @lululxvi and other researchers. Hopefully, all are safe and well. I am trying to solve  with  over a unit square along with some boundary conditions. While running...

Argument ‘sigmas’ in ‘dde.nn.MsFFN’ for a 2D (time-independent) problem

1

Hello @lululxvi and other researchers. There is a 1D example for Multi-scale Fourier feature networks in: https://deepxde.readthedocs.io/en/latest/demos/pinn_forward/poisson.1d.multiscaleFourier.html It is not clear how to give values to the argument ‘sigmas’ in...

Visualization for fourier_2d

Hi All, There is no section for the visualization of the results in the link below: [](url)https://github.com/zongyi-li/fourier_neural_operator/blob/master/fourier_2d.py Plus, what are r, h, and s in the configs section? Any idea...

Data generation for Darcy_2d

2

Hi All. The computational domain of my case is set to be [0, 1]@[0, 1]. A 30@30 uniform mesh is selected for the fine grid system, and subsequently, there are...

@jtguibas, @MortezaMardani Dear All, I have already applied FNO for a case study related to the Darcy equation using the data generated by myself (input of 30 & 30 ---->...

How to include physics constraints for a 2D Darcy problem

1

@zongyi-li Hello. Hopefully, everyone is doing well. I have already developed an FNO-based model for a 2D (xy) Darcy flow problem using generated samples. There is potential to further improve...
