Boundary condition as input for branch net in PI DeepONet

[voloddia]

Hi,
I am solving a 1D heat conduction equation and I want to use one BC (time-dependent) as input for the branch net in PI DeepONet.
In the demos, it seems that the function u must be inside pde.
Does the current code allow to feed a BC into branch net?

Hi Dr. Lu, I want to know if the advection_aligned_pideeponet_2d example solves the following PDE:
∂u/∂t + ∂u/∂x = 0
The initial condition is:
u(x,0) = sin(2πx)
Thank you!

I see an additional variable v is used for IC. I'll try the same approach with BC.
Thank you, Professor Lu.
