The tables below show the minimum, budget, and high-end system and hardware requirements for workstations and laptops necessary to achieve maximum performance with Autodesk Inventor Nastran and Autodesk Nastran. There are no special hardware requirements for the Nastran products beyond those imposed by Microsoft® Windows®.

Note: Autodesk Inventor (Standard or Professional) 2026 must be installed before installing Inventor Nastran 2026. If you are installing Autodesk Nastran on a Linux operating system, Autodesk Inventor is not required.

The Linux version of Autodesk Nastran is built on ubi-8 ( https://developers.redhat.com/articles/ubi-faq). We recommend you use RedHat Enterprise Linux 8.6 or newer of this Linux distribution.

Autodesk Nastran may work on other Linux distributions which are not officially supported. On other Linux distributions, binary compatibility of Autodesk Nastran requires a specific version, or greater, of the glibc library. Please consult your distribution's documentation to learn how to determine the versions you have installed. Alternatively, websites such ashttp://www.distrowatch.org maintain databases of the versions of components available with specific distributions. The table above summarizes the glibc library requirement.

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:

• 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.
