sorry. Didn't read your question carefully. There are multiple ways to simulate the Burgers equation in Python or Matlab.If you want to use software without going into detail use OpenFOAM....

Just to elaborate, you could possibly use finite difference, finite elements, finite volumes, lattice Boltzmann etc. The easiest would be using finite difference. However, It would be much easier to...

Same error. Just now. It was working last week.

Can you please use markdown code block to write the code? [Here](https://docs.github.com/en/get-started/writing-on-github/working-with-advanced-formatting/creating-and-highlighting-code-blocks) is some help.

hey, it is difficult to understand your problem. Can you share the entire code? You have only shared the exact solution which is not very helpful

Hey I think the forward pass for `fnn` with Tensorflow 1.x is [here](https://github.com/lululxvi/deepxde/blob/5b21146dd2c73e8df7d31acaad8b5604d30fc3e8/deepxde/nn/tensorflow_compat_v1/fnn.py#L65).

If this is a well-posed problem with a unique solution, then you are making a mistake in the implementation. Can you please share the code with us? Remember to use...

What is ```gaussian_wave()``` and `func_zero_IC`? Remember the function must take a tensor a return a tensor.

Something is wrong. This is the error. ```python [](https://localhost:8080/#) in pde2(X, U) 4 5 psi_x = dde.grad.jacobian(psi, x) ----> 6 psi_xx = dde.grad.hessian(psi, x) 7 psi_xxx = dde.grad.jacobian(psi_xx, x) 8...

Hey I think I found the issue. According to the definition of Jacobian and Hessian [here](https://github.com/lululxvi/deepxde/blob/e030a3d8d3503bfca006c505271cefa827833ec5/deepxde/gradients.py#L6), you need to use I,j to decide which column of x and y you...
