i seem to be coming up with a lot of non converging graphene tfet devices .. i am tired of retsarting my jobs ... the thing is it happens only for some bias values .. is there a way to specify a max iteration limit so it can just move on to the next bias? another question is, what will happen if it does not converge, will it just run forever ? i have a job running now at step 70, about 9 hours ... i dont want to kill it, but i dont know how long it will go on ... what can i do?
