老师们打扰了，我最近在做半导体nin掺杂类型heater的热仿真，每当扫描到3.6V的电压就会发生报错终止，报错内容如下：
WIN-IP4KCO3P6M4(process 0): Solver terminated at step 74 of 72. Error (divergence): Drift-diffusion/Poisson Newton solver failed to converge after 100 iterations.
Device solution update error ratio norm is 4.58745
Device residual norm is 0.00166607.
Residual ratio (last iteration/first iteration) is 1.25249e-005.
WIN-IP4KCO3P6M4(process 0): Warning: The charge transport solver failed to converge (Convergence Failure). A partial result will be saved. For instructions on how to troubleshoot this issue, please refer to this: online reference
WIN-IP4KCO3P6M4(process 0): The program terminated due to an error: The simulation diverged and the result is incomplete.
WIN-IP4KCO3P6M4(process 0): Error: there was an unknown parallel error. The error code is 9002, the process number is 0
我尝试过缩小CHARGE节点中mesh的大小，以及灵敏度sensitivity的大小，但仍未解决，我不知该仿真具体出了什么问题，如果老师看到的话还请麻烦老师指点迷津！
祝好！

建议你第一次扫描到71 或者70点，然后将文件保存为第二个文件专门仿真高压情况，以之前的仿真结果作为初始值：

（因故无法上传软件截屏，你应该能找到）。

然后将电压点细分更多，很可能在这个电压附件电流太强快击穿了。

 

其它请参考 Troubleshooting convergence errors in CHARGE
