Hello all,

I need help resolving this random error message I'm getting when I try to run an explicit dynamics simulation. It had been working great for a few days and now I can't run anything without this error, even starting new fresh test projects, re-opening old projects that used to work without error, restarting my machine, re-installing ANSYS, etc. Static structural simulations seem to still work fine.

Please help!

Thank you!

Luke

Hello Luke, did you install any software recently?

[Luke Saindon]

Hello,

I really haven't, I was thinking about that, I believe I saw a post from you asking someone the same question who was struggling with a similar issue as mine. I tried reinstalling ANSYS with my virus protection and everything off because I heard that might make a difference, but it didn't help. Is there any tool I can use to really scrub my system of all old ANSYS files to have a really fresh install? I feel like there are always remnents and settings after I uninstall, maybe it won't help with this issue.

Thanks,

Luke

Oh, there was one thing. When I upgraded to 2023 R1 earlier this week, a couple days before I starting seeing this error I got this install error. It let me skip it and I wasn't having any issues using explicit dynamics with the install for a couple days. Once the error started I thought maybe this was related so I manually installed the .NET package. One subsequent re-installations of ANSYS at least I didn't get this particular problem, but the Fortran error has persisted.

Did you install the exact version that the error message shows?

I have a newer Dell laptop and when I went to install Ansys, I got an error message from the installer. I had to install an older version of a package that I had a newer version of. After Ansys installed, I could install the newer package again. I don't recall the details but it wasn't what you show.

[Luke Saindon]

Yeah, I uninstalled a newer package and installed the version it asked for. The next time I re-installed ANSYS it didn't give me this error, but the Fortran error has been consistent despite all this

Luke,

Quit Workbench.

Go to this folder:  %appdata%  that will take you to a Roaming folder.

Delete (or rename) the Ansys folder.  This will force Ansys to create a new profile for you.

Start Workbench and test the issue.

Ok, I worked with our ANSYS representative to solve the problem, I wanted to post here since I’ve seen others ask similar questions and there’s never been a clear solution:

”Please go to C:\Program Files\ANSYS Inc\v231\aisol folder. Right-click on bin folder and open properties. Go to Security tab and select your email address or username or Users in Groups or usernames box. Check if you have read and write permission. Ideally you need to have full access. If you don’t see the full access, please ask your IT to provide full access to this folder.”

The above works, but also, I started just making sure Workbench always “ran as administrator” and that solved the issue as well. Silly solution, but I didn’t realize that would make a difference. I wasn’t running as admin before and wasn’t having any issues, but some sort of permission must have got changed.

Good luck,

Luke

Thanks for the reply Luke.  Yes, when installing Ansys it is required to Run As Administrator.  That is part of the installation instructions.
