Do you mean you don't know the PDE? PINN is primarily used to solve PDE. So why would you use DeepXDE or even PINN to solve such a problem? Can...
This is the wrong implementation. Try this out. ``` bc1 = dde.icbc.DirichletBC(geomtime, lambda x:0, lambda x, on_boundary: on_boundary and np.isclose(x, 0)) bc2 = dde.icbc.DirichletBC(geomtime, lambda x:0, lambda x, on_boundary: on_boundary...

@Tomandjob First of all, please do not paste codes with errors. `A=xy` is not valid statement in Python. `return 0.5dy_xx + dA_x` is also not valid. Also, when you paste...
@Tomandjob I don’t think the implementation of the normalisation condition is correct.
Why do you have multiple model compilation with different learning rate? Adam already changes the learning rate based on the momentum values. Is there an advantage of doing this?
Please use ``` your code ``` to insert your code from the toolbar provided when you write something in Issues section. So your code will look something like this. ```python...
@dmaionchi Please share your code here.
It is clear that you defined the wrong problem. Your inlet velocity doesn't even match. Please can you paste the problem statement instead of the simulation figure? Also don't forget...
