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.
SimAcademy Webinar Archive: MSC Nastran HDF5 Data Model and API
This is the second of 2 sessions on HDF5, and intended for those interested in the programmatic interface to read HDF5 data. HDF5 files can be read with multiple programming languages. The first half of this session will cover the data model. This is important no matter which programming language is used. In the second half, Python examples will be used to show how to efficiently access HDF5 data.
SimAcademy Webinar Archive: Getting Started with MSC Nastran HDF5
HDF5 was introduced in MSC Nastran 2016 (enhanced in 2017 and 2018). HDF5 is an open data model for storing and managing heterogeneous data. The database organizes MSC Nastran input and output data in a hierarchical structure. Its open format and access via multiple programming languages make it ideal for FEA applications. HDF5 has important advantages: faster access and plot generation, and is easily accessed for downstream calculations. A single file can store all results, replacing use of multiple files (XDB, OP2, Master/Dball, and punch files).
