Hello, sorry for writing in English, I can't write in French. I assume that ic1 returns some expression like i = f(t) where f(t) satisfies eqn1. To plot that, you need to extract the right-hand side of the equation, by the function rhs. I think something like this should work: expr : ic1 (ode2 (eqn1, i, t), i=0, t=0); plot2d (rhs (expr), [t, 0, 0.2]); If that doesn't work, please tell us what is eqn1, and I will take another look at the problem.
