SimAcademy Webinar Archive: Aeroelastic Response Analysis in MSC Nastran

An overview of SOL 146 aeroelastic response analysis will be presented to demonstrate the use of frequency and time domain prediction of a simple wind tunnel flutter model. The model description and actual flutter test model results are documented in the following reference (Tuovila, W. J. and John Locke McCarty, Experimental Flutter Results from Cantilever-Wing Models at Mach Numbers Up to 3.0, NACA RM L55E11, Langley Aeronautical Laboratory, Langley Field, Va., June 14, 1955). The MSC Nastran Aeroelastic Analysis User’s Guide Section 8.6 also documents the 15 degree swept wing model with constant chord and compares the predicted results of the KE-method of flutter analysis with the experimental results.

SimAcademy Webinar Archive: Patran Customization - Tailoring Your Patran Work Environment

Patran has many options for customizing the GUI and tailoring it to your needs. Topics for this session include: Startup and template files Command-line arguments Environment variables Shortcut keys Editing the toolbar RMB menus

SimAcademy Webinar Archive: SimXpert_FiberSIM Link for a Composite Panel Analysis

SimXpert and FiberSIM interconnection is a progressive link between the CAD draping and FEM analysis in respect to composite part conception phases. The first level, based on initial layups, is used for pre sizing and optimization. The second level, including draping directions and thickness variations, is used for part validation and certification. These two approaches will be presented on a composite panel case study. Topics for this session include: Introduction to FiberSIM. What is the composite CAD-CAE link process? What are the two SimXpert integration process levels? Demonstration on a composite panel.

SimAcademy Webinar Archive: Simulate Composite Damage and Delamination Using Marc and MSC Nastran

The design of composite structures has traditionally been done as a linear analysis, using Failure Indices to estimate 1st Ply Failure of the structure. More sophisticated techniques are needed to predict the performance of the structure as additional plies fail or as delaminations between plies take place. While the analysis becomes nonlinear, it is now possible to predict the degradation of the structure and its ultimate capacity. This session will examine some of the advanced composites analysis tools available from MSC Software in Marc and MSC-Nastran.

SimAcademy Webinar Archive: MSC Nastran Multipoint Constraint Equations (MPC) and Rigid Element Applications

MSC Nastran provides the engineer with various methods to define constraint conditions in an analysis model. Single point constrants (SPC), enforce a displacement at a single grid. Multipoint constrains (MPC) enforce a constraint condition that involves a number of grids. Rigid elements provide a convenient method to input more advanced MPC equations for a variety of engineering applications.

SimAcademy Webinar Archive: Results Post Processing Using Patran (Part 1 of 2 Parts)

Patran contains powerful post processing routines packaged into an easy-to-use Graphical User Interface. The Patran post processor can view many stress result types, including yet not limited to, Von Mises, Principles, Shear, individual components of stress. Topics for this session include: What is a Patran results file? How do I get the results file into Patran? How do I make a visual fringe plot of my stresses? Can I change my stress plot to look different? Do I have to look at fringe plots or are there other ways to visualize results?

SimAcademy Webinar Archive: How to Validate a CMS External Superelement (Repeat)

MSC/MD Nastran allows for the creation of a reduced, matrix-based representation of a Finite Element Model. This reduced representation is referred to as a Superelement. When creating a Component Modal Synthesis version of the Superelement, there are 3 main considerations: What DOF go on the boundary Should those boundary DOF be fixed or free, and How many component modes to retain

SimAcademy Webinar Archive: MSC Nastran Glued Contact - Leveraging MSC Nastran Technology to Expedite Mesh Assemblies and Integrate Global-Local Analysis

With MD Nastran Contact and more specifically MD Glued Contact technology, it is possible to quickly assemble non-congruent meshes and benefit the ability to integrate assemblies and integrated global-local assemblies. MD Contact Technology is simple to use and allows quick definition of contact bodies using an intuitive contact pair matrix system that allows controlling how contact bodies will behave against one another. Complete contact definition is supported by MSC’s preprocessors such as Patran and SimXpert. MD Glued contact is a subset of the contact technology integrated in all of MD Nastran linear and non-linear solutions, which can be used for typical solutions such as statics, normal modes, frequency responses and transient analyses to truly expedite system response evaluations and recover local effects within the primary structure.

This presentation will explain how flexible bodies are created and used within the context of a simple crank-and-piston example.

SimAcademy Webinar Archive: Introduction to MSC Flightloads for Doublet Lattice Aeroelastic Analysis

MSC/MD Nastran provides a robust and widely used aeroelastic analysis capability. The Flightloads product within Patran provides ample pre- and post-processing for aeroelastic analysis. This presentation will introduce the attendees to the MSC/MD Nastran native doublet lattice aeroelastic analysis capabilities and touch on several of Flightload’s core capabilities including: Doublet Lattice mesh import, creation, modification and validation Creation and verification of splines for aero-structure motion and loads coupling Instrumentation of the aeroelastic model with integrated loads sensors (monitor points) Loads visualization and Flutter mode animation

SimAcademy Webinar Archive: Pre-stressed Normal Modes Analysis Using Patran and Nastran

MSC/MD Nastran allows for normal modes to be calculated on a preloaded structure. Preloads can have a significant effect on the normal modes of a structure, changing both the frequency and mode shape. Since many dynamically loaded structures have underlying static loads, it is often desirable to include the effect of such loads in the normal modes calculations. Patran can be used to set up the correct input for MSC Nastran to perform a pre-stressed normal modes analysis.

SimAcademy Webinar Archive: Composites Capabilities in Marc

Marc has been widely used for composite analysis. Besides the classical lamination theory, Marc has additional unique capabilities in composite analysis, including: - Large element library for composite analysis - Composite material properties can be created using Patran Laminate Modeler - Parabolic distribution of transverse shear strains through the thickness - Virtual Crack Closure Technology (VCCT), Cohesive Zone Modeling (CZM), Glue Failure, Delamination Failure, and Progressive Failure for composite damage - Adaptive global remeshing for crack propagation - Simulation of composite curing

SimAcademy Webinar Archive: Academic - Using Simufact.forming, Powered by Marc and Dytran, for Metal Forming Simulations in Courses and Research

Simufact.forming is a dedicated software package for performing Finite element analysis (FEA) on all types of metal forming processes, like Forging, Cold Heading, Ring-Rolling, Extrusion, Roll Forming, Sheet Metal Forming, etc. The software is process oriented, and extremely easy to use. Because the software is also open and extendible, it is used extensively both for teaching purposes during introduction courses as for advanced Research projects. During the presentation, we will discuss and demonstrate how to use Simufact.forming, and it will be explained how the software is driving enhanced versions of MARC and DYTRAN, MSC Software’s powerful non-linear solvers. Examples will be provided how the software is being used at academic institutes around the world.
