En "Select Mesh Property" pulsamos en el icono. The element coordinate system and nomenclature are shown in figure above. CID is required, if it is used to define the element coordinate system. Otherwise, the X -axis of the element coordinate system, xelem , is defined by a line connecting GA and GB of the gap element. The orientation of the gap element is determined by vector similar to the definition of the beam element, which is in the direction from grid points GA to GO or defined by X1, X2, X3. The initial gap opening is defined by U0.

Wondering the story is on Femap and Nastran? Femap is a finite element modeling and post-processing environment. Solvers typically require strict text file-based formatting of your analysis setup, which nobody does directly anymore. Instead, programs such as Femap are used to prepare those text file inputs to the solver using a combination of a modern graphical user interface built-in functions to automate tedious tasks. Simcenter Nastran formerly NX Nastran is an actively-developed offshoot of the Nastran code base, but is one of the most common solvers for finite element analysis FEA.

Nastran is essentially the math behind FEA. As a pre-processor, Femap assists with building a model of a part, and then translates it into Nastran code. Nastran then computes the behavior. Following this, Femap reads the results and provides interpretation tools to facilitate the processing of output data. Oftentimes, the amount of information from the model is substantial, and Femap can enable a more rapid understanding of gross behavior.

An engineer uses Femap to assess part behavior at a computer workstation. Who uses it? The typical user of this software set can be a university researcher characterizing some phenomena for the first time, or an aerospace industry professional completing a standardized analysis on an aircraft part to show that it will survive the rigors of intended usage.

Femap is a very mature and refined program in comparison, and there has thus been an uptick in exposure and usage. This enthusiasm is matched by the developers and consumer who work with this amazing software product. Femap is a Windows-only application. There are a few ways to license the tool. There are ways to check out network licenses for use outside of the home network for a period of time. This is called borrowing, which Femap and Simcenter Nastran officially support as of v Before USB came around, node-locked licensing was authenticated via a parallel port dongle.

Subscription licenses are a new thing as of a few years ago. An educational license of Femap is available. These files are not compatible with normal licenses, that is, files created with an educational license cannot be opened with an install of Femap that is licensed normally.

Licenses for each can be purchased individually, but a bundled Femap with Simcenter Nastran package is the most cost efficient way to get started with FEA analysis. More licensing methods and option packages are available for advanced users. Aero, from their web address www. How does Femap compare to NX or Simcenter? Read this page for more information regarding the differences between these two programs. Where did the previous name for NX Nastran come from?

They also applied it to their own development line of Nastran.
