Engineering Desktop – Pre / Post

Comprehensive Finite Element Modeling for Experienced CAE Analysts – The pre- and postprocessor is the core of Simcenter 3D connecting all applications
Preparing a simulation model is a multi-step process of importing and editing CAD geometry, meshing and connecting components, editing material properties, defining boundary and loading conditions, and exporting to the appropriate solver data format. It’s no wonder that up to 80 percent of an analyst’s time can be spent preparing models for simulation.
Simcenter 3D drastically reduces the time you spend preparing simulation models. Simcenter delivers all the advanced meshing, boundary conditions and solver interfaces that experienced analysts expect for high-end analysis. What makes Simcenter 3D unique from all other preprocessors however, is how its superior geometry engine enables intuitive geometry editing and analysis model associativity to multi-CAD data. The tight integration of a powerful geometry engine with robust analysis modeling commands is the key to reducing modeling time by up to 70 percent compared to traditional finite element modeling tools.



Integrated Structural Analysis Solutions Powered by NX Nastran

Accurately simulate a wide range of structural analysis problems including:

  • Linear and Nonlinear Analysis
  • Dynamics
  • Durability
  • Noise, Vibrations and Harshness (NVH)

Simcenter 3D includes solutions you need for a wide range of structural analysis problems within a single user environment. Engineers no longer need one tool for linear statics, another to study fatigue, and yet another for nonlinear analysis. As a result, engineering departments can consolidate analysis tools, and engineers only need to know a single user interface. Simcenter’s structural analysis capabilities are powered by NX Nastran, the premier FEA solver for computational performance, accuracy, reliability and scalability.

Simcenter 3D also supports structural analysis solutions from other commercial finite element solvers, such as LMS Samcef, Ansys, Abaqus, LS-Dyna and MSC Nastran.



Analyze Your Product’s Response to Varying Loads

Simcenter and NX Nastran provide a full range of structural dynamics solutions, including transient, frequency, random loading and shock response. For over 40 years, dynamics simulation has been a well-known strength of Nastran, the solver underpinning Simcenter’s structural analysis solutions. By integrating NX Nastran’s renowned dynamics simulation capabilities with Simcenter 3D Solutions’ productive pre/postprocessor, you can make quick design changes and provide rapid feedback on dynamic performance.

Innovative tools let you interactively evaluate the dynamic forced responses of a structural model and quickly generate and view results graphically. Additionally, dynamic analysis results are often used as input into other types of analyses, such as motion analysis for flexible bodies. To simplify simulation workflows, Simcenter and NX Nastran provide links to motion simulation tools, such as Simcenter Motion, RecurDyn, Adams, and SIMPACK.



Calculate Product Life Using In-Depth Durability and Fatigue Analysis

Your latest design may be lightweight and look great, but will it stand the test of time? How long a product lasts in operation greatly influences customers’ perception of quality and reliability, and so the ability to predict product life early in the development process lets you more easily make the right engineering decisions. Physical fatigue and durability testing is extremely time-consuming and costly, and so the best way to evaluate product life is through durability and fatigue analysis.

Simcenter 3D Solutions help to validate a product’s structural integrity over its entire lifecycle under either simple or complex loading conditions. Analysts can use Simcenter to perform in-depth fatigue analysis and life calculations to help them determine product durability based on results from NX Nastran, Simcenter Motion, Simcenter Response Dynamics, MSC Nastran, Ansys and Abaqus solutions.
