This section details how to install Autodesk Nastran onto your system. Autodesk Nastran is supplied as a single Linux archive file that can be expanded into a set of install packages, and an installation script that supports both workstation installs and thin client installs. In order to provide compatibility with the broadest range of Linux distributions possible, both RPM packages and simple compressed folder installation methods are supported. Additionally, installation into standard user locations is now supported.
A complete installation requires two items:
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.
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.
tar xf Autodesk_Nastran_2026.0.0.F-14.0.0.203_Linux_64bit.tar
cd ./Autodesk_Nastran_2026.0.0.F
./install.sh
Or, using sudo, from a terminal that a user is logged into:
sudo ./install.sh
Please select the installation mechanism suitable for your purposes.

Installs ClicV2 licensing components and registers the product. It also provides a utility shell script at /opt/Autodesk/Nastran_2024/bin/nastran_lic_reg.sh. This script can be run to register the product and provide the license server with IP address and port (example: port@hostname).
This configuration type requires separately installing the server and the client.
To install the server
/var/opt/Autodesk/AdskLicensingService/AdskLicensingService.dataLook for a string such as "Addr":"127.0.0.1:4321", and change the IP address to the address of your server.
To install the client
<KEY ID="ADSK_SERVICE_ADDRESS">
<!--Licensing service address-->
<STRING>IPADDRESS:PORT</STRING>
</KEY>
The log level configurations below are for documentation purposes. The default mode for CLM V2 logs limited levels of messages. To enable verbose logging manually, please refer to the following details for each component.
The environment variable ADLSDK_LOG_LEVEL controls the SDK's log level. If not set, default SDK log level will be "E". To increase verbosity, create a SYSTEM or USER environment variable, and set to level T (Trace) as follows:
Valid settings
T = ADLSDK_LOG_TRACE
D = ADLSDK_LOG_DEBUG
I = ADLSDK_LOG_INFO
W = ADLSDK_LOG_WARN
E = ADLSDK_LOG_ERROR
C = ADLSDK_LOG_CRITICAL
O = ADLSK_LOG_OFF
To enable Service verbose logging, open AdskLicensingService.data in a text editor. Add key-value pair "Dev":true to AdskLicensingService.data.
{
"Addr": "127.0.0.1:12345",
"Dev" : true, // Developer (Dev) mode, default false
"AutoPickFreePort": true
}
Service generates the configuration data file in the following location:
/var/opt/Autodesk/AdskLicensingService/AdskLicensingService.data
To enable debug level logging, refer to the following table. Place a .AdskLicensingAgent-log.conf file on the end user's system, in the location specified below.
Notes
The dot before ".AdskLicensingAgent-log.conf" is required.
The default Agent log will not include debug level information.
| Platform | File name | Location |
|---|---|---|
| Linux | .AdskLicensingAgent-log.conf | /var/opt/Autodesk/AdskLicensingService/.AdskLicensingAgent-log.conf |
{
"message_pattern": "%{appname}[%{pid}] | %{time yyyy-MM-dd h:mm:ss.zzz} | %{type} | %{category}: %{message}",
"filter_rules": "*.debug=true",
"log_path": "/var/opt/Autodesk/AdskLicensingService/Log",
"console_output": true,
"file_output": true
}
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.
