Can someone help me? Does anyone know why the predicted result I got is not consistent with the real result? Below is my drawing. The yellow line is the real value, and the blue is the predicted value…

Hi Prof.Lu,
I have a little problem with the BC implementation. The Bloch periodic boundary condition is a more general periodic BC, and the 1D mathematical formula shows as follows:
$$u(0,t)cos(k)=…

Dear LuLu,
We are trying to sole the following set of equations

def de_system(x, y):
r = y[:, 0:1]
p = y[:, 1:2]

I have read the F&Q and rescale the code again and again, but the results are not good. the loss of PDE cannot be convergenced(i guess maybe the PDE's problem, but the pde has addition operation, para…

I have been trying to tweak the `wave_1D` example with different ICs and BCs. I went through all the FAQs and figured out that ICs with derivatives can be defined as `NeumannBC`s. I tried doing this i…

Just a few suggestions for how we implement domains, the first one being the
most significant:
* Implement a `time_translate` method within each domain. That way the calling

Thank you so much for this awesome library.
I've been trying to solve the forward and inverse 2D Advection Diffusion equation (ADE). The forward problem converges fine with decent accuracy. However,…

Dear Lu:
Recently, I was thinking about an inverse problem concerning the inversion of nonlinear equations. I'll use the following equation as an example.
PDE: u_t = (**K(u)**)u_xx,
I…
