SimAcademy Webinar Archive: Patran CAE Solid Modeler - Leveraging Parametric Information from Imported CAD Solids

On many occasions, CAE engineers will end up being challenged when performing meshing operations on complex solids inherited from various CAD sources. Thanks to Patran’s strong ability to convert most common CAD sources using the Parasolid engine, few engineers know they can still take advantage of the parametric information contained as part of the solid to expedite high quality meshing.

SimAcademy Webinar Archive: Academic - Vehicle Engineering with Adams

Multi Body Dynamics (MBD) simulation is a method for the study of dynamics of moving parts, how loads and forces are distributed throughout mechanical systems, and to improve and optimize the performance of these system. Finite Element Analysis (FEA) is perfect for studying linear vibration and transient dynamics, but is inefficient to analyze the large rotations and other highly nonlinear motion of full mechanical systems. MDB simulation is useful in quickly analyzing the motion and forces in such nonlinear systems. Adams/Car is a specialized environment for modeling vehicles for MBD simulation. It allows the user to create virtual prototypes of vehicle subsystems and analyze these virtual prototypes much like you would analyze the physical prototypes.

SimAcademy Webinar Archive: Patran - MSC Nastran GPFORCE/Freebody Plots in Patran

MSC Nastran supports various output requests. GPFORCE is an output request for force contributions at a node. The force contributions include reaction forces from constraints, rigid elements/mpcs, element forces from elements connected to these nodes, and applied loads. These force contributions should add up to zero for a static analysis. Using this GPFORCE output from MSC Nastran, Patran is able to sum up the individual contributions using the freebody tool. Using this tool, an engineer can either look at the GPFORCE output as a marker plot or come up with the total force or moment required to balance out the loads on a section of a model. For example, what is the total shear force and bending moment induced where a wing connects to a fuselage?

Finite element analysis (FEA) is a useful and powerful tool for applying engineering fundamentals to the design and development of products. Practicing the use of finite element analysis using real world tools is beneficial for engineering universities. With some basic knowledge of the products offered by MSC Software, faculty and students can start to use these tools effectively and gain a skill that is valued in industry while improving the results of their classes and research projects.

SimAcademy Webinar Archive: Easy5 - 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.

SimAcademy Webinar Archive: Optimization - Learn About Optimization Using MSC Nastran and Patran

MSC Nastran has extensive optimization functionality, including Sizing, Shape, Topology, Topometry, and Topography Optimization. This technology allows engineer to efficiently improve the design of complex structures.

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.

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.
