Yongnan,
I agree with your spectulation. I don't think electrical engineerings looking at this forum would have a solution for this issue anytime soon. The fast way to get help for this type of issue is submitting a service request ticket to the dedicated ANSYS installation/system/liscensing team at Home Page - Ansys Customer Portal. Please also indicates your project runs fine on other computers when submitting ticket.
Regards,
GLUO
