Many non-english speacking users have a problem with english interface and help. That's not a big problem for scince-man, but many ordinary designers and engineers can problem with start using Nastran In-CAD.
Nastran In-CAD has interface for Inventor and Solidworks and both of them had a FEA tools which are localized for a lot of different language. But SolidWorks Simulation feature list is more equal to Nastran In-CAD then Inventor Stress Analysis tool.
Autodesk can increase number of designers that will use Nastran In-CAD if create a localized interface. Even more if it also translate a tutorials and help
