NX node allows for a straightforward integration with the modeling features of Siemens NX. By inserting the NX node in the execution workflow of modeFRONTIER, the user benefits from significant enhancements conveyed to complex models. ESTECO technology multiplies the chance of raising product quality by minimizing design errors of models created within NX which combine feature-based parametric and history-free approaches. The NX Nastran integration provides the user with the ability to include finite element analysis in the optimization framework. By matching NX Node output with NX Nastran directory using the Transfer File Node designers embrace an effective multidisciplinary optimization process.
