Periodic boundary conditions (PBCs) are a set of boundary conditions which are often chosen for approximating a large (infinite) system by using a small part called a unit cell. PBCs are often used in computer simulations and mathematical models. The topology of two-dimensional PBC is equal to that of a world map of some video games; the geometry of the unit cell satisfies perfect two-dimensi… Webboundary. The function u(x,y,t) measures the vertical displacement of the membrane (think of a drum for instance) and satisfies ∂2u ∂t2 = c2 ∂2u ∂x2 + ∂2u ∂y2 = c2∇2u, where c2 …

The temperature distribution, u ( ρ, ϕ), has boundary conditions u ( a, ϕ) = T 1 when 0 < ϕ < π and T 2 when π < ϕ < 2 π . The steady state temperature distribution satisfies the Laplace equation.
In this boundary condition, the model is axisymmetric with respect to the main axis such that at a particular r = R, all θs and each z = Z-slice, each flow variable has the same value. A good example is the flow in a circular pipe where the flow and pipe axes coincide.
WebThe wave equation on a disk Bessel functions The vibrating circular membrane Recall: The shape of an ideal vibrating thin elastic membrane stretched over a circular frame of radius a can be modeled by u tt = c2∇2u, x2 +y2 < a2, u(x,y,t) = 0, x2 +y2 = a2.
