Hi every one I'm trying to solve a 1D PDE with an infinite boundary condition: rmin=50*10^(-6) d=8.9*10^(-5) sol = DSolve[{d T''[r] + ( d/r) T'[r] == I w*T[r], T[rmin] == 5, T[Infinity] == 0}, T[r], r] T10[r]...
Thanks for the trick :)
Thank you very much for these explanations :)
Thanks for your tip, I've corrected my post :)
Erf, I don't have a licence for this one snif -_- Thanks for your answer :)
