Inventor Nastran is a powerful simulation software integrated within Inventor (also within Solidworks) that allows you to optimize and predict the behavior of your designs and/or products in a fast, accurate, and flexible way before manufacturing.
In this way, the need to manufacture expensive physical prototypes is minimized and innovative products are achieved in less time. Its main advantage is the power and reliability of the software and the ease of use, since it is integrated into the CAD software (Inventor or Solidworks) and we do not have to learn how to use another interface, nor do we have to import or export files.
