My PN junction simulation was abandoned when I tried to sweep a few voltage points at -4V, -2V and 0V.
At the beginning, when I performed the simulation at each fixed value of -4V, -2V and 0V, the simulation runs OK without any problem (but it is really slow, compared with the case when I ran the tutorial example). Then I switched to the sweeping mode, the simulation runs OK at the first voltage point but was abandoned at the second value. The error message is as follows,
USSRV0086(process 0): The program terminated due to an error: The simulated result is incomplete. Please review the log files for details.
USSRV0086(process 0): Error: there was an unknown parallel error. The error code is 9002, the process number is 0
I noticed that someone has reported similar error message before, which was solved by extending the doping volume. But it might not be the case here since I can run the simulation without problems at a fixed voltage.
