Ansys

Downloading the ANSYS installation files may take several hours.  Please ensure you have a strong internet connection.  If you experience issues with the download please visit Engineering North 018 to obtain a copy of the download.

 

NOTE: YOU MUST BE CONNECTED TO THE OSU VPN PRIOR TO LAUNCHING ANSYS. This is true whether you are off campus or on campus connected to eduroam WiFi. For instructions on installing and using Cisco AnyConnect VPN, see: https://it.okstate.edu/services/osuvpn/index.html

 

(If you are using an OSU-owned PC connected to the wired OSU network, a VPN connection is not necessary.)

Downloading Ansys installation files

  1. Download Ansys at OSU's Software Distribution Center (http://sdc.okstate.edu/)
  2. Sign-in using your O-Key credentials.
  3. Choose the "Stillwater CEAT Students" role in the available list and select Continue.
  4. Choose the radio button next to the ANSYS software.
  5. Select Proceed to Checkout.
  6. Continue through the checkout process
  7. Upon checkout, you will see links for all downloads (ISOs) for Ansys
  8. NOTE that there are several download files. Download them all to your Downloads folder.

 

Installing Ansys

OVERVIEW

  • You need to run the Ansys installer as an administrator
  • For each ISO file you downloaded, you will need to MOUNT the file using your operating system before you can start or continue the install.
  • Be sure you are accessing the ISO files in the proper order (DISK1, DISK2, etc.).
  • Each release of ANSYS will have a slightly different name reflecting the year and release number (e.g., "ANSYS2023R2_WIN64_DISK1").

Installation steps

  1. Locate the ISO files you downloaded.
  2. Mount the first ISO ("ANSYSxxxxRx_WINX64_DISK1.iso) by either double-clicking the file, or right-clicking the file and selecting Mount. You will need to accept the security warning.
  3. Navigate to the disk you just mounted. It will be called "DVD Drive" and have a letter, often "D:" assigned to it.
  4. Right-click setup.exe and select "Run as administrator" to launch the Ansys installer
  5. From the Ansys installer window, select "Install Ansys Products"
  6. If it's not already selected, select "Associate Windows file extensions with Ansys..."
  7. At prompt for “Enter License Server Specification,” enter the following:
    1. Ansys Licensing Interconnect port number: 2325
    2. Ansys FlexNet port number: 1055
    3. Hostname: ansys.ceatlabs.okstate.edu

NOTE: if you have previously installed Ansys, you will not see this prompt.

 

  1. If presented with the message "Windows Defender Firewall has blocked some features...", select "Domain Networks" and "Private networks," then click "Allow access"
  2. TIP: Select only the products you need. You may need to ask your instructor or teaching assistant which products to install.
  3. Allow the installer to automatically configure your geometry interfaces
  4. Depending on the number of packages and options you selected, the installer may prompt for the next install media. There will be a box "Enter the path to the next media.”
  5. Go back to Windows Explorer and locate the first disk you mounted in step 2. Right-click and select "Eject"
  6. Go to Downloads, locate the second ISO ("ANSYSxxxxRx_WINX64_DISK2.iso), right-click and select "Mount"
  7. As in Step 3, Windows will assign a letter to the new disk. Usually, it will assign "D:" again.
  8. Return to the Ansys installer and ensure that "Path to Next Media" reflects the letter assigned to Disk 2, then click OK.
  9. Installation will continue
  10. Again, depending on the number of packages and options you selected, the installer may prompt for the next install media. Repeat steps 10-14, selecting the third ISO ("ANSYSxxxxRx_WINX64_DISK3.iso)
  11. Click Next to continue
  12. Click Exit
  13. Dismount final install disk: in Windows Explorer, right-click and select "Eject"

Running Ansys

  • On initial launch of Ansys, you will be prompted several times for firewall exceptions. Click "allow access” as you did in Step 8.
  • REMINDER: If you are off campus or on campus using wi-fi, you will need to be connected to OSUVPN prior to running Ansys.
