Title: Problem in convergence in high voltages
Post by: maj7293 on January 5, 2022, 10:58
Hello.
I would like to calculate the transport properties and in particular I-V characteristics but I have got a real problem and I am not able to converge the structure in high voltages. Most of the time, it converges in just 0% and when I am going to the high biases it doesn't.
It is strange but I have got this problem after version 2019 because I didn't have such a problem before it. I should say that I use the default values most of the time and I only change the mesh/kpoint/ bias.
I would be thankful if you help me with this.
