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. 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.

You see in beams post-processing is rather time-consuming.

You get all the code requirements like EN that dictate when something is ok and when it is not. Usually, those code-checks require calculations based on internal forces, model geometry etc. This is why a subset of software was created that simply have all the code checks automated. So you are using FEA to do static design in them and then implemented code checks to see if all is ok.

This is the easier part. A good trade-off I would say! Funny thing is that what is popular strongly depend on the region you are in. The above list shows more or less the most common ones. Selecting FEA package is a tricky thing.

This is because most of them are pretty expensive some even insanely O. I would advise you to go to Linkedin and find people that work in your industry. Then politely ask them what software do they use for FEA in their company. When you will know their answers it should be easy to select the most popular solution — buy that!

This will make it much easier for you to cooperate with others, and to get jobs for you or to find a job. Just be aware that the most expensive packages have an incredible amount of options. After all, you are paying for those! If you are not sure if you can use or even need many of them, maybe a cheaper soft will be ok as well.

Just remember that you will learn in time, and sooner or later hopefully you will need those more advanced options as well! Assuming that you want to buy a cheaper soft first which in many cases is a reasonable approach! The fact that you are good in FEA does not come from clicking speed in any given software. This means that when you will switch to another soft, you will already know what you are searching for. You will know that you need to use a nonlinear support, for instance. Then the problem is only to find an icon that generates it!Log In.

The biggest differences are that FEMAP was developed as a standalone FEM product which can take models from many different CAD systems as the starting point when setting-up Pre-Processing an analysis simulation, submit the model to the solver and then display the results Post-Processwhile the NX products are fully integrated with NX where it's basically designed to leverage the existing NX model s when preparting for an analysis run and then displaying the results, again in a fully integrated manner within the NX environment.

Granted, the technology of both products are owned by Siemens PLM Software and as such there is cooperation between the development groups and where practical, common tools and research efforts are shared, but only to the extent that it does not distract from what the two product's primary market focus is.

This approach was taken because we recognized that there are potential clients who are looking for both fully integrated solutions and ones where more flexibility is desired or where there is no choice but to seek and implement CAD-independent solutions. Now I don't know if this provided you with the answer that you were looking for or not, but considering the limited and cryptic nature of the question, this is about the best that I can do. If you need to follow-up, please don't hesitate Thanks for your long explanation.

You can still opt to use a different 3rd party solver if you wish to, but it's not necessary unless you're doing something very special where Nastran is not suitable.Log In. Thank you for helping keep Eng-Tips Forums free from inappropriate posts.

What does it do exactly? Thank you, Whyowhy. This option relieves the need to carefully define rigid elements or MPCs so as to not have a conflict of the m-sets between elements.

In addition, any redundant constraints will be eliminated.La clave: partir, partir, partir superficies!. La masa efectiva se calcula respecto a un nodo de referencia, el valor por defecto es el origen del sistema de coordenadas. Las velocidades internas o desplazamientos causan fuerzas de amortiguamiento reactivas que son irreversibles y no conservativas.

Los cuatro tipos de amortiguamiento soportados en Simcenter Nastran son el viscoso, el estructural, el modal y el no lineal. El amortiguamiento modal es o viscoso o estructural y se aplica a cada modo por separado, por tanto en ausencia de otras fuentes de amortiguamiento las ecuaciones de movimiento permanecen desacopladas.
