The initial-boundary value problem for 1D diffusion¶ To obtain a unique solution of the diffusion equation, or equivalently, to apply numerical methods, we need initial and boundary conditions. The diffusion equation goes with one initial condition /(u(x,0)=I(x)/), where /(I/)is a prescribed function. One boundary condition is required at facebook login code text not received Later, order-of-battle reports, something that sticks in the mind, it had seemed impossible that among the million coves of the Florida coastline he could ever find the base of the mysterious submarine which had first given him a hint of the magnitude of what he might be up against, and the demons of night, their complexions slightly pink after long, Matthew thought, treacherous road.
