How are the boundary conditions given in the SIMPLE algorithm on a forward staggered grid for a lid driven cavity flow?
I have a code given by my professor in which he applies the boundary conditions for the lid driven cavity flow. All the enforcement of boundary conditions I have seen elsewhere completely differ from ...

Numerically solving unbounded Fokker-Planck equation
I am wanting to solve a 3D Fokker-Planck equation of the form:
$$\partial_{t}p(\mathbf{x}, t) = -\nabla \cdot \mathbf{J}$$
where $\mathbf{J} = \mathbf{v}(\mathbf{x})p(\mathbf{x}, t) - D\nabla p(\...

Using a time-like boundary as a computer?
Question and Summary
Using classical calculations and the Robin boundary condition I show that one calculates the anti-derivative of a function within time $2X$ (I can compute an integral below)
$$\...

While solving 2D Poisson's equation, how to apply floating boundary at two edges, and Dirichlet at other two?
I have a square, at left and right edge of it; I exactly know the boundary values (Dirichlet boundary). But at top and bottom edge, I want to let the potential to float. That means I don't imply any ...
