How do I solve a 2nd order nonlinear ODE with specific boundary conditions?

[mathis314]

Hi,

I need some help,

I must solve the following nonlinear differential equation,

-k1*(c'') = -k2*(c^0.5) - u*(c')

subject to the bc,

u*(c - 0.5) = k1*(c')

where k1, k2, and u are constants,

thanks

Could try Short step Fourier method (SSFM)?
