hello all, I'm trying to solve ODE's but my computer takes a very long time evaluationg. and still not giving an answer for more than 4 hours.

so please is there anything error in my solution

deqs := {NULL
         , diff(u2(y), y, y)-((h^2/K)+m*h^2*M^2)*u2(y)+m*b*rho*h^2*GR*(c3*y+c4) = 0
         , diff(u1(y), y, y)-((1/(K*(1+k1)))+(M^2/(1+k1)))*u1(y)+k1*(diff(N(y), y))/(1+k1)+GR*(c1*y+c2)/(1+k1) = 0

Hi, Can anyone help me in solving the following system of ode, i'm new in maple and i faced some problems in using it.

the system:

diff(u2(y), y, y)+m*b*rho*h^2*GR*(c3*y+c4) = 0,

diff(u1(y), y, y)+K*(diff(N(y), y))/(1+K)+GR*(c1*y+c2)/(1+K) = 0,

-2*K*(2*N(y)+diff(u1(y), y))/(2+K)+diff(N(y), y, y) = 0

with the following boundary conditions

u1(-1) = 0, u2(1) = 0, u1(0) = u2(0), (D(u1))(0)+K*N(0)/(1+K) = (D(u2))(0)/(m*h*(1+K)), (D(N))(0) = 0, N(-1) = 0
