Hi Everyone,
I have problem with convergence when I try to simulation tunnel through vacuum. The program works well with effective mass 0.1 but when effective mass is 1, it always faces convergence problem.
I have adjust all parameter in math section like, extended precision, digits, ErrRef(electron), ErrRef(hole), solve for only one type carrier...it doesnt help. It would be very great if you can recommend me some tips to solve this problem. Thank you!
