halo ppl....i jus joined this place...an awesome place for numerical stuff...

am stuck with solving a coupled second order ode, that has both the boundary conditions as derivatives....

the coupling is between two variables U and T, and for U i have normal fixed boundary condition, (ie) i know U(a) and U(b) , but in the case of T, i know only T'(a) and T'(b) ,

am stuck in solving this, the analytical and numerical solutions are not matching..!!!

btw..the equations is bounded within the [a,b]. and the step size that i have chosen is 0.05,,,i need to get some accuracy in this case..

I would be happy to receive inputs from you ppl..

thanks in advance..

cheers..
