Testing and optimizing digital products with Siemens NX and Simcenter 3D
In times of Industry 4.0 the digitalization of the value-chain becomes more and more important. The so-called digital twin allows simulations that are very close to reality. This book provides all necessary basics to perform simple as well as complex simulations with NX and Simcenter 3D (former NX CAE). It is aimed at design engineers, CAE engineers and engineering students.

The following topics are covered in the book:
- Motion Simulation (MBD)
- Design Simulation (FEA, Nastran)
- Simcenter/Advanced Simulation (FEA, CFD and EM)
- Management of Calculation and Simulation Data (Teamcenter for Simulation)
Starting off with brief theoretical introductions each chapter contains learning tasks of increasing difficulty. Most of them are based on the CAD model of the legendary Opel RAK2.
The presented methods are based on NX 12 and Simcenter 3D, the new 3D CAE solution. Revised topics in this edition are Motion Simulation with the new Simcenter Motion solver and post-processing in Simcenter 3D (FEA).
The CAD data and calculation results of all exercises can be found online. The exercises can be completed in NX 11, NX 12 and probably later versions.

Prof. Dr.-Ing. Reiner Anderl was head of the department of Computer Integrated Design at the faculty of engineering at TU Darmstadt (DiK).
