Hi Wenlong, 

Thank you so much for your time and responses.

I did not install the MPI though, is it necessary? Because previously I can run my ANSYS just fine before.

I also follow the Aniket advice to turn off the distributed run. But it still did not solve the problem and I still face the same problem.

 Stuck on

Is it possible that the problem is on the Explicit Dynamic AUTODYN License?

Because in my different computer, after the "AUTODYN PRE-SOLVER SETUP COMPLETE." appears, usually it says license acquired or something like that. But this time it can not get the license, thus it won't continue the process.
