Hi all,

I am having  problem to solve numerically a hyperbolic equation like
u_x=-pi*u_t, u(x,0)=exp(sin(x)), u(0,t)=u(2pi,t)=1. I used the method of
lines; so I discretized the spatial domain using the centered finite
difference method and thereafter I used the implicit Euler method, but I
am still having problem after long time integration.
If anyone has an idea on how I can solve numerically my problem?

THANKS,

issa
