3.5. Product Installation

Depending on your media type, start the installation process:
For downloaded installation packages:
After uncompressing your downloaded installation packages (<PRODUCT>_<REVN>_<platform>.zip & tar), navigate to the directory where you extracted the files. Run ./INSTALL. This file will reside in the directory where you untarred the downloaded files.
For USB or DVD installations:
Run ./INSTALL which is found in the mounted location of the USB or DVD. You should not use the mounted directory as your current working directory to run the INSTALL as this may cause unmounting and ejecting issues.
The installer should be run using the absolute path which may vary depending on your platform and configuration. Common examples are:
/media/<user>/ANSYS242/INSTALL
/media/ANSYS242/INSTALL
Note: In order to eject the DVD on RedHat, you may need to use the eject command.
```
eject /media/ANSYS242
```
The license agreement appears. Select the language you want to use from the drop-down menu in the upper right corner. English is the default.
Read the agreement, and if you agree to the terms and conditions, select I Agree. Click Next, located on the right side of the screen.
Note: The question mark icon located in the upper right side of each installation screen displays an explanation of the functionality available on that screen. The letter "I" icon displays information about the release version of the installation software.
The directory where you wish to install the Ansys, Inc. products is shown in the Install Directory field. You can install the products into any directory you wish, but you must have write permissions to the directory you choose. The default is /ansys_inc. We recommend using the default directory.
The Symbolic Link option is available only if you are installing as root and is enabled (checked) by default. If you choose to disable (uncheck) the symbolic link or are installing as a non-root user, substitute the directory path where you installed the product for all subsequent occurrences of /ansys_inc in this guide.
We strongly recommend that you use the Symbolic Link option. If you do not use this option, you must install all releases into a common directory to ensure license manager compatibility and availability among releases and products.
If you have already installed the Ansys Workbench Framework for Ansoft, you must install any additional Ansys, Inc. products into the same directory.
Click Next.
If this is a first time installation, you are prompted to enter your license server specification. If you already have an existing license server specification file, you will not see this window and proceed directly to the next step.
Enter your Ansys Licensing Interconnect port number and your Ansys FlexNet port number. Defaults are provided and will work in most cases. You may need to check with your IT department to confirm that the default port numbers are valid or to get different port numbers if necessary.
Specify the hostname for your license server machine(s).
Click Next.
All products available in the installation package(s) you downloaded are listed in a tree view. A checkmark to the left of the product signifies that the product and all related "child" products are enabled for installation while a grey box indicates that some, but not all products are enabled for installation. You can expand the tree to select any additional products you wish to install.
The installation program attempts to query your license server to pre-select your installation options. If the query is successful, the following message is displayed:
Review and change the pre-selected installation options if necessary
You can select or deselect any combination of products. Ansys Workbench is automatically installed with most Ansys, Inc. products; there is no individual product selection for Ansys Workbench.
If you select the Ansys Geometry Interfaces option, you are presented with additional installation steps. These steps are completed on the CAD Configuration screens which are displayed when you click Next. For additional information on completing these steps, see Specifying CAD Configurations.
You will also see an estimate of the disk space required to install all of the selected components, and the disk space you have available. The actual amount of disk space required may be less, but if you choose to run the installation with insufficient disk space available, we strongly recommend that you review the log files at the end of the installation to verify that all products were installed correctly. Installation log files are written to the installation directory.

Note: On a first time installation, if you chose to install any Ansys Geometry Interfaces, ensure that you have also selected at least one Ansys, Inc. product as part of the installation. Installing an Ansys Geometry Interface without an underlying Ansys, Inc. product on a first time installation may cause installation errors.

Select the products you want to install and click Next.
The dates on the licensing files being installed are compared to any that may already exist on your machine. (This may take a few moments.)
A summary screen appears listing your installation selections. Review this list carefully to verify that it is correct. When you are sure all selections are correct, click Next to begin the installation.
The installation progress screen displays a status bar towards the bottom of the installation window. This status bar tracks the percentage of packages that have been installed on your computer. Depending on the number of products you have selected, the installation time required could be lengthy. You will not be able to interrupt the installation process. Please be patient while the installation completes.
Note: Clicking the View Details Progress Log button opens a second window that displays the name of each product package as it is uncompressed and installed.
Click Next to continue the installation.
The product installation window reappears with a message noting that the installation is complete.
Links are provided to access the Intel MPI and Microsoft MPI installation programs and installation documentation.
A Launch Survey Upon Exiting option is included here. Clicking Exit while the Launch Survey Upon Exiting is enabled causes your default browser to open, displaying the product survey. Disabling (un-checking) the Launch Survey Upon Exiting option and then clicking Exit skips the survey.
The Ansys, Inc. Installation Launcher appears. For this stand-alone installation, you must complete the License Manager installation (next) to run Ansys, Inc. products.

3.5.1. Specifying CAD Configurations

Selecting the Ansys Geometry Interfaces option, from the product selection screen and clicking Next displays a series of configuration screens for your geometry interfaces.

On the first screen, you are asked to select one of the following three configuration options:
- Selecting the Yes, I will make my selections option and clicking Next walks you through a several configuration steps. If you select this option, you can configure the appropriate geometry interface properties by following the steps described below.
- Selecting the No. Skip configuration. I will configure later option and clicking Next ignores the geometry interface configuration at this time. After you make this selection, the installation continues as described in the Product Installation step #8. You can use this option if you have not yet installed the related CAD programs, or do not know the requested information. If you skip these steps, you will need to configure these geometry interfaces using the Product & CAD Configuration Manager before you can successfully import models into Ansys products. See Configuring CAD Products for more information on using the Product & CAD Configuration Manager.
After selecting the Yes, I will make my selections option and clicking Next (bullet point #1 above), you are presented with a check list of the geometry interfaces. You can choose which geometry interfaces you would like to configure by enabling the appropriate check box(es). Note that the configuration is not performed for any geometry interface check box that is disabled. You will have to do that at a later time by following the steps in the Configuring CAD Products section.
If you selected the interface for NX, a third screen is displayed. In this case follow the steps below. If you did not select NX the installation continues as described in the Product Installation step #8.
If you choose the associative interface and the UGII environment variables were not set, you will need to specify the NX installation path for an existing NX installation.
Once you have completed the NX configuration, click Next. The installation continues as described in the Product Installation step #8.

3.5.2. Ansys License Manager Installation

Follow the instructions below to install the Ansys, Inc. License Manager on your Linux machine. Because you will not be using a network server, you must install and configure the Ansys, Inc. License Manager on your machine. The License Manager controls access to the Ansys, Inc. products you have purchased.

Navigate to the directory where you extracted the files. Run ./INSTALL -LM. If you downloaded the license manager installation package, this file will reside in the directory where you untarred the downloaded files. If you are running from a DVD, this file will reside in the top level of the DVD.
You may see a warning stating that if the license manager is currently running, it will be shut down. This installation assumes that you have not previously installed the products or the licensing on this machine, and you are not pointing to a network license server machine. You may safely ignore this message and click OK.
Select the language you want to use. English is the default.
The license agreement appears. Read the agreement, and if you agree to the terms and conditions, select I Agree. Click Next, located on the right side of the screen.
The directory where you wish to install the Ansys, Inc. License Manager is shown in the Install Directory field. You can install the License Manager into any directory you wish, but you must have write permissions to the directory you choose. The default is /ansys_inc. We recommend using the default directory. You must use the same directory where the products were installed.
Note: You are unable to change the installation directory for a computer that currently contains an instance of the Ansys, Inc. License Manager or Ansys Electromagnetics License Manager. To change the installation directory location, you must first uninstall any previous versions of both products.
The Ansys, Inc. License Manager is selected as the only product available to install. As with the product installation, the required and available disk space numbers are shown. Click Next.
A summary screen appears that lists the products to be installed. Because this is a license manager installation, the Ansys, Inc. License Manager is the only product listed.
Click Next. The license manager installation begins.
The Ansys, Inc. License Manager is now being installed and configured on your system. After the License Manager installation has been completed, the Launch License Management Center upon exiting option is included on the screen. The Ansys License Management Center is a browser-based user interface that centralizes many of the Ansys product licensing administrative functions. If you do not wish to launch the License Management Center, clear the Launch License Management Center upon exiting option.
Click Exit to close the License Manager Installation screen.
Click Exit to close the Ansys, Inc. Installation Manager.
Open a terminal window and navigate to your Ansys installation. The following table lists the default paths to start the Ansys products you have installed.
