Recently, I am trying to build up a model involving resolving some time delay problem like the follow (for a simple example): NDSolve[{x[t] == t, y[t] == x[t + 2], x[0] == 0}, {x, y}, {t, 1, 2}] For this one, anybody can easily figure out the solution even at first glance, but Mathematica replies me with NDSolve::ndinnt: "Initial condition Automatic[1.] is not a number or a rectangular \ array of numbers". Could anybody give me a help? Merci beaucoup!
