SimAcademy Webinar Archive: Bonora Damage Model
Finite element modeling has been widely used to predict the failure. One such technique is a progressive failure analysis (PFA). However the limitation of progressive failure analysis is that it assumes material to be linear elastic up to the point of failure. To deal with failure analysis of ductile materials there are various damage models available in MSC Marc. One such damage model is Bonora model which is used to predict the ductile damage in materials that are subjected to large plastic deformation that typically occurs in manufacturing processes.
SimAcademy Webinar Archive: Contact Pair Modeling – New Approach to Contact Model Setup in Patran 2013 with MSC Nastran 2013.1
Patran 2013 supports the new MSC Nastran 2013.1 contact pair user interface by providing a new Contact Pair Load and Boundary Condition (LBC) graphical user interface. The interface allows users to create contact pairs using individual contact property sets, or re-use existing interface definitions by referencing existing property sets. This capability, along with Patran's global property editing capability, provide a powerful, scalable UI that is suited equally well to creating both individual contact pairs, and large numbers of complex contact pairs, using common properties. Along with the new contact pair user interface is a set of tools that allow users to automatically create contact bodies and contact pairs based on user-defined criteria.
SimAcademy Webinar Archive: Nastran Embedded Fatigue (NEF) – Capabilities and Applications
Fatigue failures are often identified through testing. However, since the advent of FE based stress solvers, starting with Nastran in the 1960’s, attention has focused on the concept of FE based fatigue calculation procedures. MSC Fatigue (1990) was the first such commercial package of similar commercial FE based tools. These methods, both test and FE based, treat the fatigue calculation process as a post processing task and this has been an accepted convention throughout. Now in the recent time, MSC Nastran Embedded Fatigue (NEF) breaks this convention by coupling the stress and fatigue calculation process into one simultaneous operation. This new capability has wide ranging implications in fatigue and reliability in large mechanical engineering. By combining the two separate processes into one simultaneous process the need for any kind of intermediate data is removed. Such intermediate files can sometimes be a limiting factor in the size of model that can be handled.
SimAcademy Webinar Archive: Defining and Attaching External Super Elements Using Two Step Method
The limits on hardware resources, combined with budget restrictions (large runs and stochastic variations can be time-consuming), limits the ability of engineers to solve large, complicated problems with high fidelity meshes. A solution to these problems (both hardware and time budget), can be achieved for many models by using superelements in MSC Nastran. By using superelements, the analyst can not only analyze larger models (including those which exceed the capacity of your hardware), but he can also become more efficient in performing the analysis, thus allowing more analytical design cycles or iterations in the analysis. Another benefit of superelements efficiency can be realized when models are subjected to probabilistic or stochastic analysis by varying portions of the structure.
SimAcademy Webinar Archive: Thermo-Mechanical Analysis Using SOL 400
Thermo-Mechanical Analysis in SOL 400 has been in MSC Nastran since 2008. MSC Nastran has features of multi-discipline analysis where various analyses can be coupled or chained. Multi-physics is a thermo-mechanical bi-directional coupling. Coupling the two physics is advantageous when they are closely linked together. For example in frictional heat generation or heat generation due to plastic heating. Chaining is running the two physics in sequence. We will discuss the procedure and advantages of doing a multi-physics coupled problem and chained thermal-mechanical problems. Also look at the interaction of thermal and structural analysis. New thermal enhancements in MSC NASTRAN 2013.1 in Sequential Thermo-Mechanical with Quadratic Temperature Distribution will be covered.
SimAcademy Webinar Archive: Analysis Manager Installation and Configuration Overview
The Analysis Manager provides interface to submit, monitor and manage analysis jobs on local and remote networked systems. MSC Analysis Manager is a client-server based job-submission software package for unix/linux and Microsoft Windows operating systems. It supports MSC solvers, ABAQUS and General applications.
SimAcademy Webinar Archive: Solution Download Center and MSC Support Site - An Overview
Solution Download Centre or SDC is Electronic delivery portal for various MSC Products. This portal provides access to MSC Product installers and patches. Also, users can access product related documents and can order Media through Nextra site. MSC Support site also known as SimCompanion and this Portal gives a MSC user access to MSC support, where they can submit and manage support cases as well as can access knowledgebase articles/Product documentations.
SimAcademy Webinar Archive: Improved Performance Via BPOOL
MSC Nastran is capable of very large problems due to its state of the art numerical methods. The BPOOL capability is one such example. BPOOL improves the elapse time performance by improving CPU utilization with this I/O caching method. This short webinar will show the performance improvements of large Nastran runs due to BPOOL.
SimAcademy Webinar Archive: Key Features and Demos in Laminate Modeler
Laminate modeler is an add-on to core Patran which helps in design, analysis and analogous manufacturing of laminated composite structures. It makes data management (creation and modification) of the composite layup and plies much easier and also helps visualizing the plies.
SimAcademy Webinar Archive: A Framework for Adams/View Customization With Diverse Application Examples
Adams/View is a very powerful modelling tool allowing for a deep level of model customization and parameterization. For this, the Adams/View command language can be used to define a high level of effective modelling practice. In this presentation, Chris will discuss how this functionality has been used by him to define a layer of macro functionality to support creation and management of parameterized sub-models and/or components stored in dedicated toolkits or repositories of similar application areas.

MSC Nastran has been a primary tool for performing multi-disciplinary analysis including acoustics analysis since originating in 1973. Exterior acoustics simulation capability is important for a lot of sound propagation applications, and it is different from interior acoustics simulation in essence.
SimAcademy Webinar Archive: Marc/Mentat Model Navigator
The new Model Navigator in Mentat 2013.1 provides the user the option to easily investigate the contents of a model. The Model Navigator not only effectively provides a tree representation of the model, it also allows one to quickly move to different menus. It allows the user to quickly view the contents and to determine the completeness of the model. All menus, which can be accessed from within the Main Menu, can also be accessed from within the Model Navigator.
