SimAcademy Webinar Archive: Multimass Configuration and Usage in MSC Nastran

Typical aerospace vehicle analysis requires consideration of multiple mass cases involving different structural mass, payloads, fuel conditions and environmental conditions. MSC Nastran 2018 has a new MMC capability, also known as MASSSET, that allows for specifying mass increments to construct additional mass configurations and conduct the analysis in a single run. This eliminates the need for workarounds such as subcase dependent MPCs and overlapping grids, etc.

SimAcademy Webinar Archive: External Superelement Usage in SOL400

Prior to MSC Nastran V2018 external superelements could only be created in linear solutions 101 thru 112 and then assembled into linear solutions 101 thru 112. This was a two step process. With MSC Nastran V2018 the external superelement capability was extended to allow for superelement creation as well as assembly in solution 400. The two step process is further enhanced, to an optional three step process, by allowing for a restart of the reduction run in order to obtain data recovery of the external superelement after the assembly run has completed.

SimAcademy Webinar Archive: FEM Utilities in PATRAN

Patran Utilities are a collection of user-written tools meant to simplify and extend Patran operations, and many of them should be an important part of the FEM analyst’s toolkit. While there are well over one hundred of them now, this presentation will look specifically at the utilities to create and modify nodes, elements, and MPCs/RBEs.

SimAcademy Webinar Archive: Application of Fatigue Utilities in MSC Fatigue

Fatigue occurs when a material is subjected to cyclic loading. MSC.Fatigue has extensive capabilities to carry out fatigue analysis using different approaches including Stress life (S-N) and Strain life (e-N). Fatigue analysis results are affected by many input parameters. Utilities in MSC.Fatigue help to simplify the setup and control of these input parameters.

SimAcademy Webinar Archive: Usage of Test-Correlation Tool (MSC ProCOR) Within Patran

Test correlation tool is an analytical tool for performing mathematical modal correlation of eigenvectors between two different analytical models or analytical to test data. The tool uses DMAP Alters to alter the solution sequence and perform additional calculations in support of correlation for modal analysis using MSC Nastran Solution 103. The correlation quantities are written to op2 files which can be read back into Patran using the op2 read special tab through test correlation tool.

SimAcademy Webinar Archive: Templates and Plot Sets in Patran

Templates and Plot Sets are Patran Tools to automate the creation of results plots. Templates ensure that plots throughout an entire project or across a group have a consistent format and look, and allow to user to easily re-use a complicate plot format. Plot Sets allow the automatic generation and export of dozens if not hundreds of result plots, and produce a huge savings of time and effort if many different loads cases need to be documented and compared.

SimAcademy Webinar Archive: Vibration Fatigue Analysis Using MSC Nastran (PART1)

MSC Nastran embedded vibration fatigue life estimation, when used early in a development design cycle has the potential to greatly enhance product life as well as reduce testing and prototype costs, thus ensuring greater speed to market. This computationally efficient procedure provides life estimates orders of magnitude faster, with only a small fraction of system resources compared to traditional methods that are using Time domain. Frequency domain methods for structural analysis also offer superior qualitative information about structural response.

SimAcademy Webinar Series: How to Validate a CMS External Superelement

MSC 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 This presentation will focus on how to validate that the reduced model represented by the Superelement appropriately represents the unreduced component. A particular form of Superelements, External Superelements, will be used.

SimAcademy Webinar Archive: Analysis Chaining in SOL400

This webinar discusses Analysis Chaining in Solution 400 between a nonlinear static analysis and a nonlinear transient dynamic analysis. A demonstration of the set up will be shown in Patran. Topics discussed in this webinar: SOL400 capabilities Analysis chaining Solution strategy for transient analysis (NLSTEP) Demonstration in Patran 2016.0 Alternate format of TABLED1 Common sources of error

SimAcademy Webinar Archive: Purpose Driven FE Selection for MSC Apex

As we know, it is very important to pick the right mesh and ensure the good element quality in order to get good Finite Element Analysis Results. Apex has some exciting tools that you will get the sneak preview of in this SimAcademy Session, so that we can use to ensure good mesh and hence end up with good FEA results the first time around.

SimAcademy Webinar Archive: Adams View Scripting Examples in Python

The 2017 release of Adams View contains a new Python scripting API (Application Programming Interface). This ‘Phase 1’ of the Python scripting interface focuses on model creation capabilities; future releases will address post-processing tasks, automotive-specific functionality and more. In this seminar we will show a sampling of cmd scripts that have been converted to Python. This is not a comprehensive Python training session; the focus will be on comparing cmd & Python methodologies along with a quick Python introduction.

SimAcademy Webinar Archive: Analyzing Tuned Mass Dampers with Adams/Vibration

Adams is used to simulate highly non-linear mechanical systems across a wide range of industries, ranging from aerospace vehicles to medical devices to automobiles and robotic parts handling. These systems are generally solved in the time domain to capture the full spectrum of dynamic behaviour. Non-linear systems in Adams can also be linearized at any operating point using Adams/Linear; subsequent studies in the frequency domain are done using Adams/Vibration.

SimAcademy Webinar Archive: Nastran Contact Analysis - New Features and Tips

The Nastran contact capability in SOL 400 has been widely used by structural analysts in the last few years. The feedback from these users – what’s good, what’s bad, and what’s painful - has helped MSC to improve and mature this capability. This is demonstrated in the latest two releases, Nastran 2014 and 2016, which introduced a number of new contact features and enhancements based on user feedback.

SimAcademy Webinar Archive: Multi-Stage Simulation and PRE STATE Option in Marc

In many cases, it is necessary to analyze a nonlinear process in several stages. Each stage may involve different contact bodies and boundary conditions, but history data such as temperatures, displacements, stresses and strains have to be carried over for contact bodies to be passed from one stage to another. The pre state option is one of two methods available to transfer data from one analysis to another for multi-stage simulations. It is designed to read data from a Marc results file and to use the data as initial conditions in the new analysis. In a contact analysis, it allows the selection of contact bodies to easily apply the data to parts of the current model.
