Description
Before an Ansys license can be issued to a customer, the customer must first provide SimuTech with several pieces of information that come from the computer that will be running the Ansys License Manager. Also see License Server System Requirements if necessary.
Solution
Windows Computer (Primary Method)
- These steps must be performed from the computer that has or will have the License Manager installed on it.
- For help deciding what computer to use as your license manager, click HERE.
- Download and Run the AnsysHostInfoUtility.zip
- Select OK (You DO NOT need to fill in this form)
- Select Create File > Select a location and click Save.
- While not common, if you will have multiple license servers you will need to repeat this process on those computers as appropriate.
- Return this file to your SimuTech contact.
Windows Computer (Alternate Method)
The primary method should always be used first. If the primary method does not work, use the method below.
Warning - AWS/Azure/Google Cloud VM?
DiskID's are not always unique in these cloud environments and you may be required to provide and use a MAC address as your HostID. Becauase MAC addresses are not static by default in these cloud environments, your IT Administrator must configure the cloud VM with a static MAC address before gathering your Host Info.
If a static MAC address is not set, the MAC address will change when the server is restarted and subsequently, your license server will not start because the HostID in your license file will not match the HostID of the computer.
- First, select the computer you will use as your license manager. Click HERE for help.
- These steps must be performed from the computer that will have the License Manager installed on it.
- Copy, paste and run commands below in a Windows command prompt.
- Tip - you can copy and paste all these commands at once.
-
hostname >>AnsysHostInfo.txt
vol c: >>AnsysHostInfo.txt
getmac /v >>AnsysHostInfo.txt
- Browse to C:\Users\YourUserName\AnsysLicenseInfo.txt > send this file to your SimuTech contact.

The information below helps SimuTech Support staff translate this information into the correct HostID and HostID Type. 
Linux Computer (Primary Method)
Warning - AWS or Azure VM?
If you are using a Linux VM you are required to use a MAC address as your HostID. MAC addresses on Azure and AWS are not static by default and will require your IT Administrator to perform additional steps set a static MAC address. This needs to be done prior to gathering the host info.
If a static MAC address is not set, the MAC address will change when the server is restarted and subsequently, your license server will not start because the HostID in your license file will not match the HostID of the computer.

- Untar the archive file:
tar xvf linx64.tar
- Run the GetLinX64Hostid utility:
./GetLinx64Hostid
- Complete the fields when prompted (customer number, company name, name, phone, etc)
- You may use the term NA in these fields.
- If you have multiple MAC addresses, contact your IT Administrator and confirm which will be the primary one used.
- While not common, if you will have multiple license servers you will need to repeat this process on those computers as appropriate.
- Return all created licserver.info files to your SimuTech contact so that all required license files can be created.
