Siemens NX 10 Nastran

This textbook explains how to perform computer aided analysis by using NX 10 Advanced

Simulation with NX Nastran solver. It starts with analyzing a cantilevered beam and builds up the reader’s understanding of the concepts and process of structural analysis.

Each chapter contains a typical example of analysis and is followed by a quiz to summarize

the topics. In addition to the tutorial in each chapter, more commands and concepts are explained at the end of the chapter to help improve the reader’s understanding. The method for concluding an analysis is presented at the end of the tutorial for typical cases.

It is assumed that the readers of this textbook have no experience with Siemens NX 10 interfaces and modeling process. The first chapter explains how to use the basic utilities and concepts in NX 10 regarding menus, part navigator, roles, customer defaults, manipulation

of 3D model, etc. In the second chapter, the process of 3D modeling in NX 10 is explained via a tutorial. In the third chapter, more commands and tools for constructing and modifying 3D models are explained. It includes topics such as constructing a sketch, extruding and revolving the sketch, boolean operations, datums, copying objects, synchronous

modeling, etc. Readers who are familiar with creating a 3D model in NX 10 may choose to skip the first three chapters.

In Chapter 4, the cantilevered beam is analyzed in a tutorial. Terms and concepts regarding

the structural analysis are explained at the end of the chapter. In NX Advanced Simulation,

we use up to four files during the process: FEM file, SIM file and two part files. The contents of each file and how to manage the files are explained at the end of Chapter 4.

The chapters have been structured to learn commands and tools in NX Advanced Simulation

and understand which commands are required for the simulation of engineering concepts.

The final four chapters, Chapter 22 through 25, cover advanced solution processes such as buckling, normal mode, heat transfer and fatigue.
