SimAcademy Webinar Archive: Interface Elements Using MSC Nastran

There are a number of techniques taught in MSC training classes covering how to get surface meshes to match up. This is necessary for maintaining a load path and maintaining a smooth stress gradient across different pieces of geometry. Interface elements are used in MSC Nastran for cases where the mesh does not match up across two surfaces. In the past, the only option for this was the RSPLINE. The RSPLINE does transfer load, but stresses are not very smooth across an RSPLINE. MSC Nastran 2005 introduced a number of new options: CINTC and glued contact.

SimAcademy Webinar Archive: Model Checks for Dynamic Analysis

MSC Nastran has been a primary tool for performing dynamic analysis since originating in 1972. Over the years, there have been many user-developed tools for performing model checks. MSC Nastran has incorporated many of those tools into the Case Control Commands. These, along with some additional lessons-learned, will be presented in this Webinar.

SimAcademy Webinar Archive: MSC Nastran Dynamics Solution Setup and Result Processing Using Patran

Frequency Response Functions (FRFs) represent responses at desired DOFs of a component due to unit loads at specified DOFs for that component. This basic concept has been around for many years. This presentation extends the normal FRF on a component basis, plus the subsequent assembly of these components—including test components.

MSC Flightloads provides a user-friendly GUI for performing aeroelasticity analysis using MSC Nastran. This is a continuation of a series of aeroelastic webinars presented in this SimAcademy webinar series. This presentation focuses on the process from start to finish in setting up an aeroelastic trim analysis for MSC Nastran along with the corresponding results processing.

SimAcademy Webinar Archive: Sinda/Thermica for Spacecraft and Ground Solar Heating

The Sinda family of thermal design products has been relied on by aerospace and high technology companies worldwide for 50 years. THERMICA is a comprehensive thermal modeling system developed by spacecraft thermal engineers at EADS Astrium. Sinda for Patran seamlessly integrates Patran and Thermica. It leverages Patran’s powerful and versatile modeling environment and a does a smooth data exchange between Thermica-Sinda and Patran.

SimAcademy Webinar Archive: Modeling Fluid Power Systems with Easy5

Fluid power systems are widely used in various applications including industrial, aerospace, automotive, off-highway, rail transportation, and defense. Modern constraints such as cost, efficiency, time to market, and reliability make designing and analyzing these systems even more critical for a successful product cycle. Modeling and simulating electro-hydraulic/fluid power components and systems in EASY5 will help you determine the performance and behavior of those systems. Furthermore, it will also enable you to become more familiar with your system and give you a better understanding of the underlying physics behind the system performance. This can lead to shortened design iterations, fewer physical prototypes, elimination of guesswork, and a reduced expenditure of time and money.

SimAcademy Webinar Archive: Nastran – MSC Nastran Linear Buckling

In addition to being a general purpose FEA code, MSC Nastran has been used extensively for performing dynamic analysis and buckling analysis since its inception in 1963. Buckling is an instability that causes failure before the material yields.

SimAcademy Webinar Archive: Nastran – N is for Nonlinear as in SOL400

MSC Nastran is the most widely used and generally recognized as most trusted Finite Element Analysis (FEA) solver. MSC has invested many man-years of development time in incorporating ‘state of the art nonlinear analysis technology’ that came from Marc Corporation, into a new Nastran nonlinear solution (SOL400). This SOL400 combines and further enhances traditional nonlinear solution sequences- SOL106 (Nonlinear Static) and SOL129 (Nonlinear Transient) that existed in MSC Nastran.

SimAcademy Webinar Archive: Adams - Integrating Control Systems from MATLAB and Easy5 with Adams

The proliferation of control systems embedded in mechanical systems means that it is hard to find industry applications where control systems are not present. From industrial automation to active vehicle dynamics to spacecraft dynamics there are controller systems interacting with complex mechanical systems. Designing controller behavior based on a linear representation of the mechanical system is commonly practiced and, with some care, produces reasonable results. Investigating the true dynamic interaction between controllers and complex, high-fidelity mechanical systems is the domain of Adams and MATLAB (or EASY5) via Adams/Controls.

SimAcademy Webinar Archive: Advanced Thermal Modeling Tools for Aerospace, Automotive, and Green Energy Applications

This presentation shows some of MSC Software's advanced thermal modeling tools including new products to be released in 2011. Models are built in Patran 2011 with orbital heating or terrestrial solar loads computed by Thermica which transparently integrates into Patran. Temperatures are solved using the Sinda thermal analyzer and its Patran preference. Demonstrations models of a spacecraft in orbit with articulating solar panels, shielding of an automobiles exhaust system and a solar water heater will be presented and discussed.

SimAcademy Webinar Archive: Academic - Integration of PATRAN with CAD Packages

This SimAcademy session is intended primarily for the university audience and covers the basics of file import and geometry manipulation through the new Feature Recognition tool. File/Import allows for the importation of model files from a number of different sources, such as a Patran database, Patran 2.5 neutral file, MD Nastran input file format, or one of several CAD formats such as: CATIA PROENGINEER UNIGRAPHICS PARASOLID ACIS IGES FILE PATRAN NEUTRAL FILE STEP FILE Once the model is imported, it can be meshed, edited using the core tools in PATRAN, or by the Feature Recognition to change/delete features such as holes, fillets and chamfers. This lecture will introduce Feature Recognition as an editing tool.

SimAcademy Webinar Archive: Shock Spectrum Analysis

Shock Spectrum Analysis and Response Spectrum Analysis are methods used to estimate maximum dynamic response of a structure. The advantage of these methods over a conventional transient analysis is economy and simplicity. The only major calculation step is obtaining a sufficient number of normal modes to represent the entire frequency range of the input excitation and resulting response. The presentation will show different how to create response spectra for a given transient response and also how to analyze structure subjected to response spectra input.

SimAcademy Webinar Archive: Hyperelastic Material Modeling and Characterization in Marc

Elastomers are widely used across several industries, including automotive, aerospace, machinery, and biomedical. Their increased use can be attributed to their wide availability, low cost, and even more importantly because of their unique customizable properties that need to be understood. Using highly-accurate hyperelastic material models, high performance, and easy-to-use numerical analysis techniques enables you to simulate reality through nonlinear finite element analysis can help correctly capture fit, form, function, and manufacturability of the product. This allows you make better design decisions earlier in the product's life cycle, and allows you to explore and optimize product performance more quickly through less-expensive virtual (non-physical) testing.

SimAcademy Webinar Archive: Use of Residual Vectors in Modal Solutions

MSC Nastran has been a primary tool for performing dynamic analysis since originating in 1972. When performing a modal transient or modal frequency response analysis, the truncation of the normal modes can influence the dynamic results. This is a common aspect of performing modal dynamic solutions, and pretty well understood. However, the modal truncation can also impact quasi-static response in the structure. This effect has been mitigated in the past using modal acceleration techniques. For the past decade, MSC has offered residual vectors as a replacement for the modal acceleration method.
