| Windows Operating System(desktop workstations or laptops) | 64-bit Microsoft Windows 10 |
| Linux Operating System (Autodesk Nastran only) | RedHat or CentOS 7 or 7+, glibc 2.17 or 2.17+libstdc++/compat-libstdc++ 5.3.1 or 5.3.1+ |
| Network Card | Required for network installation with FlexLM licensing for all workstations or laptops. |
Linux Operating System Requirements
The Linux version of Autodesk Nastran is built on CentOS 7. We recommend you use version 7 or newer of this Linux distribution. This release will also work on Red Hat Enterprise Linux 7 versions. Support for Red Hat Enterprise Linux 5 and 6 has been discontinued.

Autodesk Nastran may work on other Linux distributions which are not officially supported. On other Linux distributions, binary compatibility of Autodesk Nastran requires that a specific version, or greater, of two core system components be installed. These system components are the glibc library and the libstdc++ library. The version of the libstdc++ library is usually tied to the version of gcc on your system. Additionally, newer Linux distributions may have moved the required libstdc++ libraries to a “compat-libstdc++” package. Please consult your distribution’s documentation to learn how to determine the versions you have installed. Alternatively, websites such as http://www.distrowatch.org maintain databases of the versions of components available with specific distributions. The table below summarizes the requirements.

We recommend you upgrade to the latest stable version of Linux. The improvements in performance, security, and reliability may be beneficial – even if you only use Autodesk Nastran occasionally. Installation requires a number of standard system utilities such as gzip, tar, sed, grep, and bash which are most likely installed by default on your system. If you find these are missing, please ask your system administrator to install.

There are many types of hardware that will allow you to use Inventor Nastran and Autodesk Nastran. Proper choice of hardware, however, can often make the difference between frustration and productivity. Here are a few suggestions:
Autodesk Inventor Nastran 2021 Free Download
- Add more memory (RAM) above the minimum configuration. This will allow you to specify more memory for the Nastran products and reduce the likelihood of memory thrashing (excessive paging of virtual memory to disk).
- Hard disk space recommendations are general guidelines only. User requirements can vary considerably, especially when using large models.
- Purchase or upgrade to the latest versions of Windows. The improvements in performance and reliability will more than outweigh the initial cost – even if you only use the Nastran products occasionally.

Workflow: Basic software installation
Installation steps may vary according to your product, installation environment, operating system, and other factors. In general terms, you prepare your system, choose installation options, install the product, and launch it. Installation varies for products using improved installation services; for more information, see Does my product use the improved installation services?
Important: These instructions outline the steps you take to install. They don’t contain troubleshooting information. If you run into problems when you try to install, see the troubleshooting section for your product on the Autodesk support site.

Planning and installing software licenses for your network
This workflow leads network administrators through the steps for planning, installing, and configuring licenses for Autodesk products.
- Plan your software license
Choose a license server model, select network servers, and check the system requirements for Network License Manager. - Install Network License Manager
Install network license management software on Windows, macOS, or Linux systems. - Obtain and install a license file
Collect information about your network license server, generate a license file, and save it on your server. - Configure your network license server
Create a debug log file, configure your network license server, start it, and confirm that it’s running. - About software license options and tools
To maximize the number of available licenses, learn which options are available and what they do.

Overview of license types
Administrators manage three types of licenses, according to the subscription type. These license types are authenticated differently.
- Named user licenses, based on the customer’s Autodesk Account, are automatically authenticated when the customer first runs a product after signing in to Autodesk Account.
- Standalone licenses are tied to specific devices and use serial numbers. When customers first run the product, standalone licenses are authenticated either silently by Autodesk servers or when customers are prompted to enter a serial number.
- Network licenses, managed with Network License Manager (NLM) software, are authenticated by pre-configured network license servers. Sometimes, customers may be asked to give license server information when they first run a product.
You can identify your license type for each product in the Products and Services section of Autodesk Account.

Choose a network license server model
If you have a network license, choose one of these license server models:
- Single server. All network licenses are installed on one server.
- Distributed server. Network licenses are split up and installed across as many servers as you choose.
- Redundant server. All network licenses are installed on three different servers, with one as active and the others as backup.
Autodesk Inventor Nastran 2021 Free Download
Select network servers
After you choose a network license server model, select one or more network servers from which to manage your licenses.
- Servers must be accessible to all client machines and available whenever licenses are requested.
- They must run on a supported operating system in a stable network that is not frequently restarted or shut down. Frequent restarts can interfere with license management.
- Servers should communicate with ports 2080 and 27000-27009, the ports NLM uses. Although these ports are configurable, changing them may cause conflicts with other applications. Do not change the ports unless necessary.
Note: Your network can include Windows, macOS, and Linux servers in any combination.

Check system requirements
Check the system requirements for NLM and make sure that your hardware and operating system are compatible with NLM.
