Download Autodesk Inventor Interoperability Autodesk Inventor Nastran is a CAD-embedded, general-purpose FEA tool powered by the Autodesk Nastran solver. The new Nastran In-CAD offers a wide range of simulations spanning multiple analysis types, delivering another high-end simulation in a CAD-embedded workflow that works within Autodesk Inventor and SOLIDWORKS to help engineers and analysts make great products. This program, Nastran In-CAD, can also handle different elements in the same analysis, mixing surface models with solids or beam elements in the same analysis. This is to understand better and have more confidence in the draft design proposal. 64-bit from Direct link
