SimAcademy Webinar Archive: Patran - Learn About Advanced Patran Meshing Techniques
Patran has always had very robust tools for meshing. In recent years, more functionality has been added to the program, allowing it to perform well with modern CAD parts. Solid meshing of CAD assemblies can be done in less time than ever. In the case of the new Mesh on Mesh, the original surface geometry is not required – a new surface mesh can be generated from an input file containing only 2D elements. There are also new tools to make it easier to fix surface incongruencies and other geometry issues that, in the past, would’ve taken more effort and time to resolve.
SimAcademy Webinar Archive: Patran - Perform Random Analysis Using MSC Random (Patran) and MSC Nastran
MSC Random performs random analysis of structures subjected to random environment. MSC Random is a tool developed by field engineers after soliciting feedback from customers. The program interactively calculates random response of a structure. The power spectral density function (PSDF) can be plotted interactively. Furthermore, these plot data can be exported to Microsoft Excel. The fringe plots of nodal and element responses--including Von-Mises stresses, strains, and element forces--can be created within MSC Patran. The relative PSDF of nodal response can also be created interactively.
SimAcademy Webinar Archive: Marc - Apply Local Adaptive Meshing for Improved Nonlinear Analysis
Adaptive meshing is a tool in Marc that is used to automatically re-mesh some or all of a finite element model during an analysis. As analysts attempt more and more highly non-linear simulations they often encounter extreme element deformation that standard solvers have difficulty handling. Adaptive meshing can be used to prevent many problems associated with these excessive element distortions such as poor quality results, job termination due to elements turning inside out, and undesirable contact penetration. Adaptive meshing is very useful in many applications, especially those that experience high levels of deformation including manufacturing simulations, seal applications, and forming problems.
SimAcademy Webinar Archive: Adams - Create Smarter Adams/View Models Through Parametrics
Adams/View contains a rich set of parametric model creation utilities. Creating 'intelligent' models that update based on Design Variable settings is quite straightforward. Using parametrics to capture engineering best practices or to simplify model alteration processes is both logical and efficient. This session of SimAcademy will start by investigating element properties and understanding the basics of the Adams/View expression language. Navigating the documentation to locate functions and understand syntax usage will be discussed. Creating and using Design Variables will be considered along with tips, tricks and example applications.
SimAcademy Webinar Archive: MSC Nastran - Defining and Using Superelements in MSC Nastran and Patran
We will discuss MSC.Nastran’s Superelement capability and a demonstration of how to set up an superelement problem within Patran.
SimAcademy Webinar Archive: Academic - Using Marc in University Courses and Research Involving Nonlinear Mechanics
As part of MSC’s “University FEA Bundle” of software, Marc and Mentat combine to provide a graphically-rich environment for modeling and simulating nonlinear mechanics. This session of SimAcademy is designed to enable university course instructors and students to extend their analytic knowledge of solid mechanics to address complex problems posed in nonlinear mechanics that cannot be solved with existing closed form methods.
SimAcademy Webinar Archive: Academic - Using Adams in University Courses and Research Involving Kinematics and Dynamics
This session of SimAcademy is designed to enable university course instructors and students to see how they can go beyond static CAD by visualizing how things move – and why. We will start from the fundamentals of F=ma for simple one-dimensional (1-D) systems and progress to 3-D systems, highlighting how Adams provides insight into both kinematics and dynamics (kinetics).
SimAcademy Webinar Archive: Composite Ply Stress Recovery in Frequency Response
Ply stresses in complex frequency response were previously not available in MSC Nastran. This feature is now available in MSC Nastran 2012+. This webinar will focus on the methodology used to recover ply stresses subjected to dynamic loading (frequency and transient response - Sol 108, 109, 111 and 112). Since there is no post processing currently available for complex ply stresses, a utility program is written to post process the complex ply stress results in Patran.
SimAcademy Webinar Archive: Rapid Flex Body Generation in Adams/View Using Adams/ViewFlex
Adams/ViewFlex allows users to quickly and easily create flexible bodies without leaving the Adams/View environment. This new feature, introduced in the Adams 2012 release, streamlines the creation of Modal Neutral File (MNF) representations of linear elastic bodies in Adams. With some basic FEA knowledge one can easily define attachment points, specify mesh and material properties and much more, all within the Adams/View environment. This seminar will focus on the various ways that Adams/ViewFlex lets you create high fidelity component representations quickly and easily.
SimAcademy Webinar Archive: Adams - Getting Started with Adams/Solver Subroutines
The Adams/Solver Function Expression language provides a comprehensive environment for the mathematical modeling of complicated forcing functions, motions and the like. Whenever possible the Adams user should strive to use the built-in functions of Adams/Solver to model system inputs, but there are times when unique inputs must be implemented in user-defined code. This is the role of the Adams/Solver subroutine interface, which allows for user-written subroutines to be coded in Fortran or C. This session of SimAcademy will run through the basics of subroutine creation and usage in Adams/Solver. Examples will include subroutine type selection, compilation, parameter input usage, utility subroutines, best practices and more.
SimAcademy Webinar Archive: Segment to Segment Contact in Marc
In order to improve contact accuracy, Segment-To-Segment contact algorithm was introduced in Marc2010 and its capabilities enhanced in the subsequent Marc releases. The contact model set up is much easier with this method as there is no consideration required to select the touched and touching bodies. The method also gives rise to better contact stress distribution and better overall results. This webinar discuss about the benefits, set up, description, and limitations of Segment to Segment contact in Marc.
SimAcademy Webinar Archive: Beyond Eigenvalues and Eigenvectors
Dynamic analysis is an integral part of CAE. It is very crucial to know the dynamic behavior of a system. For many years, MSC Nastran has been a de-facto standard in the industry to perform dynamic analysis. The first step towards dynamic analysis is to find out system’s natural frequencies. Though Normal modes analysis in MSC Nastran is a basic solution, it reveals a lot of useful information. It is challenging to mathematically model and predict correct dynamic response of a system. Engineers need to validate the accuracy of results for complex systems. With ever increasing model sizes it is important to perform the simulation in an efficient manner. This presentation provides an overview of tools available in MSC Nastran to deal with these aspects of dynamic simulation.
SimAcademy Webinar Archive: Sinda Visio Office Toolkit and Thermal Studio
The Sinda family of thermal design products has been relied on by aerospace and high technology companies worldwide for 50 years. MSC Sinda Visio Office Toolkit and Thermal Studio are two modules of Sinda which are included in MSC Sinda basic package. Sinda Visio Office Toolkit allows you to set up a network model of a ‘Thermal System’ by creating diffusion nodes that represent ‘lumped masses’ of various sections of a large model, connecting them to each other with conductive, convective or radiative resistors, heat sources in a flow chart like manner. When you run the network model, it generates a Sinda file automatically. Thus a 20 or 30 node models can be run with many what if scenarios to get a ‘feel of the thermal system behavior’ during initial design phase.
