NASTRAN Interface has multiple forms to import results form different programs including: FEMAP neutral format (*.neu), PUNCH format (*.pch).With these features, NASTRAN Interface makes it posible to pre/post-process a model in the same envarioment using multiple visualization techniques depending on the eligible interpretation of the model. Very useful are color maps, structure deformations drawings, graphic visualization of a stress in bars, reactions vectors, stress vectors, and many others.
