ANSYS Student 18.2 never solves

I am using the student version of ANSYS Mechanical version 18.2.  Every time I open up the program and try to solve a problem the solution bar gets stuck at "Preparing the mathematical model". This happens even when I have a simple beam with a fixed support at one end and a transverse load at the other. What I am saying is that I highly doubt this problem is due to the complexity of the solve. I have even left my computer working on the solution over night (for the simple beam problem I described before) and it is still stuck on the "Preparing the mathematical model" part. 

I have even gone so far as to uninstall and then re download ANSYS three times and it still does not work. 

I have no idea what to do about this and I cant find anything online. If someone can help me figure this out this would be great! I need help! 

Thank you

How odd!

How much RAM and disk space do you have available on your machine?

Thank you for the response!

I have attached an image with the specs of my computer. It should be more than fast enough to handle the solutions.



I also have over 200GB of space on my hard drive so that should be fine.


any ideas?

Another piece of info:

When I got to solve the solution information is always blank. I attached a screen capture to show this.

I also have this problem. A few days later it started working randomly but today it is stuck on the same thing again. Extremely frustrating. I have seen it work on my computer before so I know my computer can handle it. It must be something that is wrong with the student edition program files.

Looks like it is related to mpi processes being blocked. Could you please turn off the firewall or go to tools>Solve Process Settings>Advanced>Uncheck "Distribute Solution (if possible)". See if that helps.

Now fluent keeps failing to startup. Do you think this issue is related?
