An error occurs in SimpleODE

[vivaldi370]

Thanks for your awesome work, but I found a few minor bugs in simpleODE.

First, the values x_BC and x_PDE are passed in the wrong places：

def loss(self,x_BC,x_PDE):
    ...
# train neural network
for i in range(steps):
    loss = model.loss(x_PDE,x_BC)# use mean squared error

However, def f_BC is

def f_BC(x):
  return torch.sin(x)

rather than

def f_BC(x):
  return torch.zeros_like(x)

So this code will still get the correct result when this error occurs.
The code corrected by me has been uploaded as an attachment
simple_ode.txt
, which may explain this bug more clearly.
