Installation

Files Required for Installation

A complete installation requires two items:

• A package containing all the necessary files, which will have a file name similar to Autodesk_Nastran_2026.0.0.F-14.0.0.203_Linux_64bit.tar. Exact version numbers may vary from that shown here.
• Licensing information. This will be the internet name of your Autodesk Nastran license server, either in the form of a numerical IP address, or machine.domain.com.

This package does not provide an Autodesk License server. Autodesk provides license servers for a number of operating systems. Your retailer can provide the appropriate license server for your requirements.

Installation

This section provides the steps required to install Autodesk Nastran. The following package names are provided as examples. Please adjust the following commands and packages based on the packages you have been provided.

1. Unpack the provided package using the following command. This command will create a sub-directory in your current location that contains the files necessary to install Autodesk Nastran 2026 (The package version numbers may be slightly greater than shown below).

   tar xf Autodesk_Nastran_2026.0.0.F-14.0.0.203_Linux_64bit.tar

2. Change your working folder to the created folder:

   cd ./Autodesk_Nastran_2026.0.0.F

3. Start the installer by entering the following command. If you wish to do a system install you will need to start the installer from a terminal prompt as the superuser or using the 'sudo' option. If the installer detects insufficient privileges to perform a system install, it will reduce the install options presented to performing only a Thin-client or custom install. On a terminal in which a standard user or superuser is logged in, start the installer like so:

   ./install.sh

   Or, using sudo, from a terminal that a user is logged into:

   sudo ./install.sh

4. Please read and accept the licensing agreement provided. A copy of the licensing agreement can be found after the install at: /opt/Autodesk/Nastran_2026/adlm/EULA.txt.
5. Depending on the privilege level of the user starting the installer, three possible installation mechanisms will be presented to the user.
   • The first mechanism provides system installation using RPM packages. Autodesk Nastran installs into the location /opt/Autodesk/Nastran_2026, which complies with the Linux Standard Base (LSB) specifications.
   • The second option provides a system installation for thin-client server using RPM packages. This option only installs licensing components that will be used by a thin client installed using the third option.
   • The third option permits an install into a user-defined location. Upon selecting this option, you will be prompted to specify a location to install into. This option is useful for users installing for thin-client scenarios and for individual users installing into their own home folders. This option is presented to users installing without superuser privileges.

   Please select the installation mechanism suitable for your purposes.

The Linux version of Autodesk Nastran requires a network license. The installer will display a screen requesting the details of your license server. This needs to be provided in the format [port]@1.2.3.4 or [port]@machine.domain.com, where [port] is optional and only required if a non-standard port was used in the license server setup. If you do not know your license server details, or wish to change it at a later date, please enter a temporary value of @127.0.0.1. The network server in use can be changed later by directly editing the text file: /opt/Autodesk/Nastran_2026/bin/nastran_vars.sh.

Autodesk Nastran requires particular environment variables to be set prior to execution. An option will be presented during the install which enables all users to have their environment variables adjusted automatically when they first create a terminal. This option creates a link in the system settings folder to enable automatic setting of the required environment variables. It is highly recommended that you enable this option. Alternatively, two other methods are described if this mechanism is unsuitable for your intended usage.
