Finite element stuff

 

You can obtain here an executable for Windows * operating system that solves a hyperbolic equation.

Unzip the file and run the program. In the program, one can edit functions for input to the solver and

see the animation of the discretized solution. The discretization is in regular grid (in x-y space) where

the system is solved via Choleski method, while the solution proceeds in time via Crank-Nicolson

technique. For the beginning, open Test1.fdb and solve the equation by choosing 'f' for the force,

'u0' for initial position and 'u1' for initial speed. The reference (i.e. exact solution) is function 'u' and

you can use it later in order to compare graphically the errors of the solution.

Enjoy!
