System of PDE

Hi,

Is anybody able to help me in solving the following system of first
order partitial differential equations with Mma 2.2.3 for Windows :

D[y1,t] + a1* D[y1,x] = f1 (y1,y2)
D[y2,t] + a2* D[y2,x] = f2 (y1,y3,(y3)^2,y2*y3)
D[y3,t] + a3* D[y3,x] = f3 (y3*y2,(y3)^2)

where y1,y2,y3 are unknown functions that depends of: t,x
and 0<= t <= Infinity, 0<= x <= L ; a1,a2,a3 are const.. Boundary and
initial conditions are const (>0) or functions of t.

I will be happy to get any help of this problem

Thanks

Boguslaw Ptaszynski
