SimAcademy Webinar Archive: Overview of the Modules

Module is a standalone Bulk Data section typically representing a component of an overall assembly. Modules are analogous to part superelements without reduction. Modules allow the user to assemble multiple Bulk Data sections to form a single MSC Nastran input file. Modules offer a complete range of flexibility to the user when it comes to defining connections to a Module. In this webinar we will discuss use and importance of different bulk data entries used to define modules. We will see different options available to post process the modules results. In this webinar we will discuss how to define modules and how to set up analysis file for Nastran using modules approach. This session is NOT a substitute for formal training, many more options and scenarios available with modules.

SimAcademy Webinar Archive: Power Tools for Adams Customization

This webinar presents a Macro Organizer Plugin for Adams View that users can download from the MSC SimCompanion website. Specifically, this plugin makes it easy to organize and extend Adams View functionality with user-written macros.

SimAcademy Webinar Archive: Contact Modeling in Adams – Detailed Analysis of Contact Parameters and Integrator Settings

The CONTACT statement in Adams is used to model collisions between bodies within a larger MBD simulation. This unilateral force has a zero value when there is no penetration between the geometries and has a positive value when penetration does exist. The CONTACT statement supports multiple contact types, dynamic friction, 3D solid geometries and 2D geometries.

SimAcademy Webinar Archive: Inherent Strain Approach in Marc

This SimAcademy webinar discussion will be on using a different approach to such simulations, based on inherent strains (which contain the summation of the thermal strains, plastic strains, creep strains and phase transformation strains). Using inherent strains, the analysis reduces to an elastic structural analysis, which is much faster than its coupled Thermal/Structural counterpart.

SimAcademy Webinar Archive: Modal Stress Recovery using Adams Durability & Distributed Loads for Linear Flexible Bodies in Adams

A Modal Neutral File (MNF) is a conduit to take reduced model information produced via component modes analysis into multibody dynamics (MBD) software such as MSC Adams. The modal information obtained from an MNF file is used in the MBD software to represent flexibility. This presentation will attempt to describe this process.

SimAcademy Webinar Archive: Advanced Options in Superelements

In this webinar we will discuss MSC Nastran’s advance option to define superelements and how to set up superelement problem for Nastran. This session is NOT a substitute for formal training, many more options and scenarios available with superelements.

SimAcademy Webinar Archive: Isosurfaces in Patran's Insight Tool

Patran’s Insight is an interactive results postprocessing tool that complements Patran’s core Results application. It has been a fixture of the program for a long time. In the 2019 version of Patran, it was ported to the new QT Interface. In this short webinar, we will cover some of the basics of Insight, but we will focus the discussion primarily on Isosurfaces, one of its most useful tools.

SimAcademy Webinar Archive: Modules Instantiation in MSC Nastran

This webinar discusses how Modules can be used to create multiple instances of a primary Module with a process called Module Instantiation. Modules are created to reduce the reliance on the preprocessor for copying, translating, rotating or mirroring an existing primary Module. The enhanced MSC Nastran interface will be demonstrated with a very simple flat plate model which shows how pre-processor modelling time is reduced. Finally, the pros and cons of this approach will be discussed.

SimAcademy Webinar Archive: New Methodology of Bolt Pre-tensioning Introduced in MARC/Mentat 2018 version

Efficient Process of Defining Multiple Bolts with Preload is illustrated. The presentation includes demonstration of the two different bolt pre-tensioning methods available in Marc/Mentat.

SimAcademy Webinar Archive: Uncovering The Gems in Your MSC Nastran Output Files

In this webinar, we will explore the "gems" in different output files generated by MSC Nastran. These files contain clues and little gems of information, which can help us figure out different issues.

SimAcademy Webinar Archive: The New Material Data Fitting Capabilities in Marc

This seminar will review the existing and new data fitting capabilities in Marc and discuss the Ogden-Roxburgh damage model, followed by a live demo of experimental data fitting for a rubber material with damage, viscoelasticity and plasticity.

SimAcademy Webinar Archive: Subtleties of CBUSH Element in MSC Nastran

This webinar will focus on how to hand calculate the element forces for a Nastran CBUSH element from the grid displacements. The emphasis will be on CBUSH elements connected to non-coincident grids, and the matrix manipulations necessary within Nastran to maintain rigid body properties for the element.

SimAcademy Webinar Archive: FRF FBA Scope and Understanding Responses

FRF FBA is a two-step process; first user needs to generate the FRF's from the individual components of assembly. Subsequently do the solution from FBA. The frequency response function (FRF) and FRF-based assembly (FBA) are not new to MSC Nastran users. FRFs can be used to represent components. This capability facilitates the computation of the FRFs of individual components and also the subsequent computation of the FRFs of an assembly of such components from their individual FRFs.

SimAcademy Webinar Archive: Rotordynamics Capability in Recent Years in MSC Nastran

For the past few years, MSC Nastran has supported 1-D rotor dynamics using beam/bar elements, which is widely used by turbines, jet engine, and airplane manufacturers. The rotor dynamics capability allows the user to perform static analysis, obtain real and complex eigenvalues, and determine frequency response and transient response. The 1-D implementation had the limitation that it cannot be used to model complex rotor geometry and the blades in this analysis are treated as rigid. The rotordynamics capabilities within Nastran are improved significantly from Nastran 2013 release. This webinar will summarize these features from Nastran 2013- Nastran 2018.

SimAcademy Webinar Archive: Automatic Contact Methods with MSC Nastran/Patran

In the modern industries, the product structures like airplanes, automobiles, and so on are becoming more and more complicated with many parts. It becomes, very challenging and difficult for users to establish the contact relationship between contact bodies. This webinar discusses Automatic Contact Methods which can be set up either in Patran or Nastran. A demonstration of the set ups will be shown using Patran followed by the Nastran BDF. Finally the pros and cons of both methods will be discussed.
