## SimAcademy Webinar Archive: The F06Reader Utility Introduction and Usage for MSC Nastran

F06 Reader 2016 is an MSC Team effort to read Nastran output text files and produce a friendlier, modern and more useful format of important Nastran information. The intent with this tool is to display information, help the user diagnose problems and link to additional resources. At this time it is not intended to retrieve and perform user defined calculations with the data.

## SimAcademy Webinar Archive: Nonlinear Solution Setup Highlights Using SOL400 in MSC Nastran and Patran

SOL 400 is a set of application modules in the MSC Nastran system that pairs the full features of MSC Nastran with the advanced nonlinear capabilities. More and more companies are using sol400 for their nonlinear analysis needs. In a nonlinear problem, the stiffness of the structure depends on the displacement, and the response is no longer a linear function of the load applied. As a result, nonlinear problems require incremental solution schemes that divide the problem up into steps calculating the displacement, then updating the stiffness. This presentation is to help users setup and be successful at getting the first converged solution faster.

## SimAcademy Webinar Archive: Frequency Response Usage in Nastran and Patran

Frequency response analysis is a method that allows users to analyze a structure’s response to a steady- state oscillatory excitation. In this type of analysis the excitation is explicitly defined in the frequency domain. The structure is subjected to an oscillatory sinusoidal loading with an amplitude at a specific frequency. Similarly the response occurs at the same frequency as the loading. Examples of oscillatory excitation include rotating machinery, unbalanced tires and helicopter blades.

## SimAcademy Webinar Archive: Introduction to Cyclic Symmetry Using MSC Nastran and Patran

MSC Nastran is widely used in different industries for different applications. Its unique capabilities, including linear statics, linear and nonlinear dynamics, Acoustics, Aeroelasticity, Optimization and multi-physics, allow users to tackle difficult simulation problems.

## SimAcademy Webinar Archive: MSC Explore – A Post Processing Tool for Multiple Subcases

MSC Explore is a tool developed to enable rapid identification and visualization of critical design results from MSC Nastran analyses inside MSC Patran. MSC Explore enables the user to look at MSC Nastran results across multiple load cases and multiple results files; instead of the traditional one load-case at a time approach. MSC Explore uses an efficient GUI interface for selecting and viewing results across all results. The single tool supports Static, Transient and Frequency Response Analyses Results.

## SimAcademy Webinar Archive: Adams - Contacts Overview, Best Practices, and Tips

The Adams CONTACT formulation makes it easy to create impact forces when geometries come into contact. Adams allows for two different contact formulations (IMPACT and restitution) and supports both analytical and CAD geometries. Contacts produce discontinuous forces and the Solver behavior is greatly influenced by the contact parameters (stiffness, damping, exponent, etc.) as well as modeling choices and integrator selection. This session of SimAcademy will provide a detailed examination of the CONTACT statement for general background. Best practices related to geometry selection, contact parameters, modeling techniques and integrator selection will be considered with an emphasis on building models that solve efficiently and robustly.

## SimAcademy Webinar Archive: Introduction to Fatigue Analysis Using MSC Fatigue Software

Fatigue failures in structures occur when structures undergo cyclic loading even when the nominal maximum stress values are much less than the yield stress limit of the material used. If the loads are above a certain threshold, microscopic cracks will begin to form at the surface of the members of the structures. Cracks will grow and eventually reach a critical size and structures would collapse suddenly. There have been many catastrophic structural collapses, all over the world, attributed to fatigue failures. MSC Fatigue software is being used by many companies (Aero, Automotive and other industries) all over the world for the fatigue analyses of their products.

## SimAcademy Webinar Archive: Patran - Introduction to PCL Programming

Engineering can be an iterative process. PCL is a powerful tool that can be used to enhance Patran functionality by integrating with external processes and creating custom interface objects. PCL can also be used to automate repetitive Patran tasks, thus saving time on engineering revisions.

## SimAcademy Webinar Archive: Introduction to Finite Element Analysis for University Course and Research

This presentation is tailored primarily for the university with limited experience in using MSC finite element tools. It is intended to provide an overview of finite element analysis using Patran and MSC Nastran. The topics covered in this presentation will include: Patran graphical user interface MSC Nastran input file structure Structural elements Loads and boundary conditions Materials Element properties Analysis submission Basic postprocessing

Adams/Car and the Baja and Formula SAE Templates allow students to rapidly create a full dynamic model of their student competition vehicle and simulate complex dynamic events. These templates provide a pre-modeled vehicle that typically only needs hard point, shock, tire, and mass properties defined to begin running simulations and doing design studies. After some introductory setup information, this SimAcademy session will discuss general vehicle modeling and simulation concepts. An example vehicle design problem will then be solved to demonstrate how Adams/Car is used to make real-world design decisions.

## 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.

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.
