Undergrad Verification regarding Neumann conditions at time derivative

Click For Summary
SUMMARY

The discussion centers on the application of Neumann boundary conditions in the context of the 2D heat equation. Specifically, the question posed is whether a Neumann condition applied at x = 0 remains valid when considering the time derivative. The consensus is that Neumann conditions, which specify the derivative of a function at the boundary, do indeed hold at the time derivative, affirming the continuity of the boundary condition across time.

Hi, just a question regarding neumann conditions, I seem to have forgotten these things already. I think this question is answerable by a yes or a no.

So given the 2D heat equation,
243463


If I assign a neumann condition at say, x = 0;
243464


Does it still follow that at the derivative of t, the condition still holds? I mean:
243465
Thank you!
