Implicit solutions can also be devised. Recall from equation (2.45) that we have a linear relation among the values of u(xk) and the neighbors involved in the derivatives. Actually, if equation (2.45) is extended to all the points within domain Ω, we get a linear system that we write ...
A solution to Laplace's equation has the property that the average value over a spherical surface is equal to the value at the center of the sphere (Gauss's harmonic function theorem). Solutions have no local maxima or minima. Because Laplace's equation is linear, the superposition of any ...
Laplace EquationIn this paper a Cauchy problem for a two-dimensional Laplace equation under the condition that an exact solution belongs to a compact set is considered. We solve this problem as an operator equation. The errors of the operator and the right-hand side are found under a ...
In conical coordinates, Laplace's equation can be written (1) where (2) (3) (Byerly 1959). Letting (4) breaks (1) into the two equations, (5) (6) Solving these gives (7) (8) where are ellipsoidal harmonics. The regular solution is therefore (9) However, ...
• Since the equation is linear we can break the problem into simpler problems which do have sufficient homogeneous BC and use superposition to obtain the solution to (24.8). Pictorially: Figure 2. Decomposition of the inhomogeneous Dirichlet Boundary value problem for the Laplacian on a recta...

4 THE LAPLACE EQUATION 2. Steady-State Temperature Problems The above problems for the Laplace equation are illustrated by the steady-state solutions of the 2-D and 3-D heat equation. By a steady-state function u, we mean a function that is independent on time t. Thus, u t ≡ 0. In...
Some two-dimensional problems of elastostatics are governed by Laplace’s equation. Using the terminology of elastostatics, if the face loads and body loads are not self-equilibrating, even when the displacement at infinity is restricted to zero, displacements in the near field will be infinite....
