I want to solve and visualize system with a parameter using the following code:
L = 10
sol = ParametricNDSolve[{y'[t] == Sqrt[(k^4)/(y[t]^4) - 1],
y[0] == 0, Integrate[y[x]^(-2), {x, 0, L0}] == L/(k^2)}, {y[t],
k}, {t, 0, L0}, {L0}]
Manipulate[Plot[Evaluate[y[L0][t] /. sol], {t, 0, L}], {L0, 2, 3}]
However, I got an empty plot and no error or warning message. Why can it happen? If there is no solution, should not there be an error message?
