This section explains how to install Ansys, Inc. products, including Ansys client licensing, as well as the Ansys, Inc. License Manager.
The default installation expects you to be logged in as root. You can install as non-root; however, if you are not logged in as root, you will not be able to set the /ansys_inc symbolic link and may potentially experience permission problems. The inability to set the /ansys_inc symbolic link will in no way inhibit your ability to run Ansys, Inc. products; it is provided as a convenience.
If you do not use the /ansys_inc symbolic link, you must install all releases into a common directory to ensure license manager compatibility and availability among releases and products.
If you did not use the /ansys_inc symbolic link, you must replace all references to /ansys_inc/v242 or <install_dir> with the actual installation path you used.
Before You Begin
We recommend that you have the following information available before you begin this installation:
An account on the Ansys customer site. If you do not have an account, you may register at www.ansys.com/customercommunity to receive your own account.
Your license file from Ansys, Inc., saved to a temporary directory. For more information, see Registering the License Server.
Open port numbers for both the FLEXlm and Ansys Licensing Interconnect. Defaults are 1055 and 2325, respectively. To verify that these port numbers are available, open a command line and enter the following command:
netstat -a -t
You will see a list of active ports. If 1055 and 2325 are listed, they are already in use and cannot be used for Ansys, Inc. licensing. In this case, you will need to specify different port numbers where indicated later in this installation.
Your local machine's name, to specify as the license server.
Note: In order for Ansys products to operate normally, it is necessary to have name resolution (communication by host name) between the license server machine and the client machine.
You should also verify that you are running on a supported platform. Ansys, Inc. products support 64-bit Linux systems running Red Hat, SUSE Linux Enterprise 12, SUSE Linux Enterprise Server 15, CentOS and Ubuntu. For current platform information, see the Platform Support section of the Ansys Website.
Verify that you have sufficient disk space to download, uncompress, and install the products you are installing. Approximate disk space requirements for each product are shown in Disk Space and Memory Requirements.
If you have any problems with--or questions about--the installation process, log a Service Request on the Ansys customer site to have a Systems Support Specialist assist you.
