NEi Nastran EditorNEi Nastran Editor

The NEi   Nastran Editor is an industry unique tool that gives engineers greater control over their Nastran FEA models and results. Features such as advanced editing, context-sensitive input, and dynamic help greatly increase productivity and results reliability from the start. Built-in tools such as the trade study generator, a basic optimization utility, give users quick insight into the effects of design changes. Real-time results are displayed through an integrated post-processor allowing users to visualize results as they are generated during the solution sequence. These features combined make the NEi Nastran Editor an indispensable tool for designers and analysts alike.

Customer Feedback

"One of NEi Nastran's greatest features is the Editor. Processing directives and parameters are easily managed in a tree structure in a side window and all of the Nastran keywords and statements are linked to context sensitive help file. Even the error codes may be quickly and automatically looked up in the reference manual, which makes debugging a breeze. This is the sort of feature that Nastran has always needed."
