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: Academic - Introduction to Adams/Car for Formula SAE
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: Adams - Optimization, Design of Experiments, and Monte Carlo Studies Using Adams/Insight
Adams/Insight is a tool that is used for quickly and easily setting up multi-run studies on your Adams models. This session of SimAcademy will start with a broad theoretical overview of the Optimization, Design of Experiments (DOE) and stochastic (Monte Carlo) methods which are available in Adams/Insight and Adams/View (Adams/Car).
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.
SimAcademy Webinar Archive: Introduction to Flight Loads
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.
