Autodesk discontinues Autodesk Nastran, AKA NEi Nastran

February 23, 2018

Effective March 27, 2018, the Autodesk Nastran solver is being discontinued. New sales and multi-year renewals are phasing out this year, with annual renewals being discontinued next year. Existing subscribers will have access to the technology until the end of their current contract.

We recommend all customers begin finding a replacement solver well before the end of their current contract. Siemens PLM remains committed to offering both perpetual licenses for NX Nastran as well as flexible FEMAP & NX Nastran subscription options, giving analysts a number of methods depending on their contractual needs.

For those who don’t recall, NEi Nastran was an engineering analysis and simulation software product of NEi Software (formerly known as Noran Engineering, Inc.) Based on NASA’s Structural Analysis program NASTRAN, NEi Nastran was used with all major industry pre and post processors including FEMAP, NEi Fusion, and NEi Works for SolidWorks. It was acquired by Autodesk in May 2014.
