Description:

I have been using ansys 16 on windows 7 professional and window 7 ultimate without any problems.

Problem:
Then on one of my systems (optiplex 9020) I have installed Ansys 17 with windows 7 ultimate. Every thing went fine, except Fluent 17. Which was not starting and giving me this error :

Quote:
Error: eval: unassigned variable
Error Object: rp-host
Solution:
I have installed windows 10 professional (enterprise also checked and working. Education version is also supported as per ANSYS update) and did not find any problem with it. But as I can see that Ansys is still supporting windows 7 (professional and enterprise), but i thought to upgrade to window 10 instead of installing windows 7 professional.

Hope this will be helpful to every one.

I just installed Fluent v17 on Windows 7 ultimate and it worked on all my machines. These are regular desktops and not any fancy workstation, a factory Dell XPS 9050 and two custom built machines running 1st gen i7's.

Although Windows 7 (professional and enterprise) are supported versions for ansys 17.0. May be it due to some problem in windows installation. This is also confirm by LuckyTran as he is running ansys 17 on unsupported version of Windows 7.

I would recommend you to shift to windows 10 professional or windows 10 enterprise.

Regards

I also have it working on Win7 Enterprise. But on Enterprise it is very easy to run into problems depending on who set up the OS.

I forgot to mention, I installed Fluent and only the required CFD-post and nothing else. Can the problem be caused by one of the add-ons for CAD software or maybe another program? CATIA for example?

Windows 7 Enterprise with ANSYS v17 here too. Everything works properly though (FLUENT, ICEM, WB, ANSYS Meshing, even Polyflow).

Stop watching, your PCs will work better

I tried upgrading to v17 and v17.1 and have not got it to work on my Windows 7 machines. High end Dell T 7910s. Design Modeler won't work. Gives error message. CFX with Intel MPI only works on one of four computers. Going to downgrade to v16.2.

I think the problem has something to do with the way the MPI binds the processes to the cores. I wonder if Windows 10 and 7 do something differently with that, or if it's all controlled by the start-methods.ccl file

Fixed it. For some reason Intel MPI wants to map network drives, so it hangs up the solver if there is something funny about your network drives. You can just delete that command from start methods. I think. No problems so far...

Hi,

I am having the same difficulty on Win 7 Ultimate, SP1. You said you sorted this out, Cristofe. Could you, please, give me the details, so I can do so myself?

Many thanks and best regards,
Ed Moses

I actually have it running on Windows 7 pro, and enterprise just fine now. Initially I thought there might be a compatibility issue with win 7 and the newest MPI software. But that wasn't it. I had to edit the start-methods.ccl file to get CFX to work. Also make sure everything you install you install Run AS Admin.

I am also trying to install ansys 17 on win 7 pro and getting this error,

error: problems were encountered while attempting to start the following process ansysli_server.exe, ansysli_monitor.exe, ansyslmd.exe

There is no anti virus program on this machine and i added exception for the above files in window firewall.

Any help will be greatly appreciated.

This is usually a problem with user account privileges. You always? need to launch the license utility with admin privileges. Make sure you installed Ansys as an admin.
