fea solid modeling, meshing, and analysis

Anyone can take an object, mesh it, apply some boundary conditions and, with a click-of-a-mouse, generate some colors. However, it’s a bit more challenging to transform a mishmash of color into a verified and accurate simulation.

This webinar discusses how to idealize solid geometry into efficient numerical models that are quick to run and can generate accurate results.

Speed is important; achieving an answer that you can trust often means running the same model dozens of times. So, we will cover how to take a chunk of junk, mesh the impossible, hex what is hexable and tet the rest. Then we’ll discuss element quality and how to make it run quickly.

Fatigue failure is the fracturing of a given material due to cracks induced from cyclic stresses, and most engineering failures are caused by fatigue. What makes fatigue so dangerous is that the stress levels that cause fatigue damage are typically much lower than the yield strength of the material.

This webinar discusses fatigue and how you can use FEA to prevent failures by using stresses extracted from the model to calculate the expected life of a product based on the material properties. We discuss how to create a robust clean mesh that will allow for accurate contouring of stresses so that meaningful values can be extracted and used for fatigue calculations.

We are pleased to inform you that FEMAP v2020.1 has been released and is available as a full install. If using a version released prior to FEMAP 2019.1, please download the full installation of FEMAP 2020.1 MP1. Download and installation of FEMAP 2020.1 is not required to install 2020.1 MP1.

FEMAP v2020.1 is the latest user-focused release of FEMAP containing many features and enhancements requested by our users worldwide, along with important fixes for known issues.

The first update many users will notice is that all icons throughout the application have been modernized with the result being a more contemporary look and feel. Another item of note is that all Palette buttons have been replaced with a color block showing the current color, along with an indication of the line style, for the entity.

The latest version also introduces support for Monitor Points and Direct Matrix Inputs (DMIGs) for the Simcenter Nastran and MSC Nastran solvers, which are part of the new Simulation Entities subset of entities. Additional support for the Multi-Step Structural (SOL 401) and Multi-Step Nonlinear Kinematic (SOL 402) solution sequences in Simcenter Nastran is also now offered.

A unified architecture for the display of labels in the graphics window has been implemented to offer greater consistency across Performance Graphics and Legacy OpenGL Graphics. In addition, control of the format used for the display of digits for Load Vectors, non-zero Constraints, and several items which appear when viewing results has been enhanced to offer more flexibility.

Feature Editing via the Meshing Toolbox now offers a Smart Select option, along with 5 additional sub-options, which are used to automatically select additional geometric entities for more robust geometry manipulation. Also, an alignment option has been added to the Washer operation of the Geometry Editing tool to align the split lines of the washer pattern to a user-defined vector, tangent to a curve, or perpendicular to a curve.

This seminar introduces the world of automation and optimization accessible through FEMAP’s Application Programming Interface (API). FEMAP provides a robust set of finite element modeling and post-processing functionality. At times, however, you may need a specific capability that is not included in the standard product. The FEMAP API lets you customize FEMAP to meet your specific needs.

Now, programming can be an intimidating topic, but the goal of this seminar is to provide a beginner’s guide. We start with the most basic “Hello, World!” example, then explore a selection of existing (and incredibly useful) programs available to all, and finally take a look at some complex real-world applications. In addition to showcasing the available tools, we provide a road map to learning the FEMAP API.

We are pleased to inform you that FEMAP 2019.1 has been released. FEMAP 2019.1 is available for download from the GTAC FTP server.

FEMAP 2019.1 is the latest user-focused release of FEMAP containing many features and enhancements requested by our users worldwide.  The latest version introduces automatic generation of pyramid elements to transition from portion of the model meshed with hex elements to portions of the model meshed with tetrahedral elements. A new Select Visible icon button has been added to the standard entity selection dialog box to facilitate selection of only items which are currently visible in the active view.

For those performing Aerodynamic Flutter analysis with Simcenter Nastran or MSC Nastran, FEMAP 2019.1 now supports import of displacement results of the aero mesh on the aero panels from the printed results file. Libraries now allow the user to specify a Personal library and/or a Shared library, or use entities included in the Femap Standard Libraries. Finally, FEMAP 2019.1 includes the ability to sweep line elements into planar elements or planar elements into solid elements by following the edges of elements which constitute a mapped mesh, even if non-uniform.

Vibration analysis is a huge topic and is easily the second most common type of FEA analysis after basic static stress analysis. Within the field of vibration analysis, the most common type of analysis is that based on the linear behavior of the structure or system during its operation. That is, its stress/strain response is linear and when a load is removed, the structure returns to its original position in a stress/strain free condition.

Although this might sound a bit restrictive, it actually covers a huge swath of structures from automobiles, planes, ships, satellites, electrical circuit boards and consumer goods. If one needs to consider a nonlinear response of the structure during operation, there exist codes such as LS-DYNA that can solve for the complete nonlinear vibration response. But that is not simple or basic and is left for another seminar sometime in the future.

We've compiled all of our seminars and white papers from over the years into this one comprehensive document on vibration analysis.
