How do I use the finite difference method with M = N = 20 to obtain a plot of the solution of
\nabla2u = 1, 0 < x < 1, 0 < y < 1,
u(x,0) = x(1-x), u(x,1) = x(1-x), 0 \leq y \leq 1,
u(0,y) = 0, u(1,y) = 0, 0 \leq y \leq 1.
Hi
I am trying to solve a nonlinear differential equation with the use of the finite difference method and the Newton-Raphson method. Is there anyone that knows where I can find some literature about the subject?
I am familiar with the use of the finite difference method, when solving...
Hi
The equation is:
\frac{dP}{dt}-A*\frac{{d}^2P}{dx^2}-B*\frac{dC}{dt}=0
dP/dt=A*d2P/dx^2 was solved using a finite difference method. If the function C(x,t) is known, is it possible to solve the whole equation by using the finite difference solution as a supplement to the complete solution...

I'm just having trouble getting started. I can do the analytical part on paper, but I don't know...
I'm going to take a finite difference linear and non-linear PDE course next semester. I'm wondering how enjoyable the material is, and how difficult it may be. I'm actually looking forward to the fact there may only be one test throughout the semester, if any, and it's a mid-term. The rest of...
To the moderator: please move this to the section on differential equations if you think it would be better there.
I'm looking at a reaction-diffusion equation of the form
\frac{\partial u}{\partial t} = \frac{\partial^2 u}{\partial x^2} + f(u),
where, e.g., f(u) = u(1-u) for the...
Fiber Grating Using Finite Difference Method
I have to solve the Fiber grating coupled-equations using FDM. These equations are coupled each other and strange inital conditions. That means ode45 from the MATLAB library function doesn't work here!
I am totally fresh in numerical analysis...
1) Using a similarity variable, the boundary layer equations for a two-dimensional, incompressible flow over a flat plate can be written below:
2f'''+ff''=0
The boundary conditions are:
a) f ' (0) = 0, no slip at the wall
b) f(0)=0, solid wall
c) f ' (n) goes 1 as n goes infinity...
