Hello dear members of the sci.engr.control newsgroup.
I'm working on a string vibration problem dealing with differential equations.
I'm searching for a SCILAB program that simulates the response of a string length L=1 (Omega=] 0,1 [) under an excitation F (X, T) =chi (X) cos (wt)
- chi indicates the function characteristic of the interval ]a,b[ on an interval of time [0, T].
This program have to make it possible to visualize on the same graph the evolution in time of three approximate solutions:
- the numerical solution obtained by applying the method of superposition of modes (decomposition on K first clean modes),
- the solution obtained while discretizing in space by the method the finite differences.
It seems that is a classical problem that had to be well probably already written. You know where I can find it please?
Many Thanks.
