This file is generated using an ipython notebook, which can be easily installed using Anaconda see the installation section for more detail. Also, I use! So for example, in windows we can run dir on windows or ls on linux to show the directory contents. I am using windows 7 operating system for work with Abaqus, and I use Linux Mint for generating the blog page.

To install a minimal python, I recommend miniconda as a package maanger. Once miniconda or is installed, install these packages by running these commands in a windows console and following the prompts. Packages that a needed to replicate my results are included in the article when they are needed. For developers, I'd recommend a more complete python installation that includes an IDE Integrated Development Environmentlike spyder.

A commercial license is prohibitvley expensing, but for students out there a nearly full functioning student edition is available herebut is limited by node count and no user subroutines.

Abaqus Scripting User's Guide - 9. You can also use field output to generate an X—Y data plot. Only complete sets of basic variables for example, all the stress or strain components can be requested as field output. Each data value has a location, type, and value. You use the regions defined in the model data, such as an element set, to access subsets of the field output data. Figure 9—3 shows the field output data object model within an output database. Individual variables such as a particular stress component can be requested.

Depending on the type of output expected, a HistoryRegion object can be defined for one of the following:. The output from all history requests that relate to a particular point or region is then collected in one HistoryRegion object. Figure 9—4 shows the history output data object model within an output database.

In contrast to field output, which is associated with a frame, history output is associated with a step. This python snippet will show a user dialog box asking for a number and it will calculate the square root of it.

We can see that the version of python that abaqus uses is older, but has most of the modules we need. We can also easily create aniamtions directly from abaqus. Using a python module, we convert the avi to an animated gif.

The gif file format is really handy. We can simple load the gif file just like we loaded png to show the animations. This is handy, but the real problem at hand is accessiblity. Abaqus is good software, but expense. Some short-term goals I have is to look into some open-source pacakges that I can run some more complex models in. Toggle navigation if curious: then learn.A simple finite element analysis code for 2D elasticity problems.

The code uses as input simple-to-create text files defining a model in terms of nodal, element, material and load data.

The code is written in Python and it depends on numpyscipy and sympy. It has been tested under Windows, Mac, Linux and Android. To specify through a GUI the folder where the input files are stored you will need to install easygui. To easily generate the required SolidsPy text files out of a Gmsh model you will need meshio.

It is easy to use. The code allows to find displacement, strain and stress solutions for arbitrary two-dimensional domains discretized into finite elements and subject to point loads.

The code is organized in independent modules for pre-processing, assembly and post-processing allowing the user to easily modify it or add features like new elements or analyses pipelines. It was created with academic and research purposes. To install SolidsPy open a terminal and type: pip install solidspy.

Mar 17, Jul 4, Jan 28, Feb 12, Mar 12, Apr 5, May 14, Pycalculix is a tool I wrote which lets users build, solve, and query mechanical engineering models of parts. The tool is a Python3 library, which uses the Calculix program to run and solve finite element analysis models. With it you can see and understand part stresses, strains, displacements, and reaction forces.

It is great for design studies. You could run many versions of your part where you change a fillet, or wall thickness, and record the stress impact. It is also good for calculating stress concentration factors. Because simplicity is minimized, Pycalculix is a good educational introduction to FEA. Do you have any plan to extend you project on 3D models? I agree that developing a python interface in 3d would be a good next step. Installed Anaconda and then py calculix.

But do not know how to run your example. Can you kindly describe how to run a simple example. Youtube video would be very useful. Put your work details in yahoo calculix forum. I conduct research in structural design optimization under uncertainty.

Your pyCalculix is exactly what I have been looking for the optimization of small problems and for my students to get started easily. I have a couple questions for you: -Why did you decide to use Python 3 and not Python 2? I wrote my optimization and uncertainty analysis tool using Python 2 and was curious on the advantages of version 3. Do you plan on moving to three-dimensional analysis?

All the required libraries I need are available in Python 3. My main goal is to have the ability to import and export parts from the tool, and have the ability to run thermal, structural, and thermal-structural analysis, and autodetect and include contact between parts.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. So far I came across sfepy. Although, it is a fully functioning FEM package, I was wondering if there are any alternatives? I use this library frequently, and i recommend it highly.

It is a mature, stable project current stable version is 2. The documentation and working sample code are excellent. It's also relatively for a specialized numerical library simple to install; the only dependencies are NumPy, and PySparse which are also dependencies for sfePy. If you have tried to install this library in the past and had difficulty, you might want try again.

The reason i say that is Trillinos the distributed processing library for FiPy is now a separate package though i would still recommend using Trillinos if you want to parallelize FiPy computations.

The only problem is that fipy doesn't use the finite element method.

It uses the finite volume method. They are not at all the same thing. So is the finite difference method if you want to be very general. But I did not say they weren't unrelated, I said they were not the same thing, and they are not.

Yes the both discretise the weak form of common PDEs, but the way the discretisation is done is very different. The original question was about frame analysis - classic direct stiffness FEM with beam or truss elements and joints. That sort of analysis can't be done with the FVM. I use FiPy a lot myself, but it is no way a finite element package, and the methods used are in no way the Finite Element Method. You should check out FEniCStoo.

Many checks are also performed to verify that your model is correct.

Using the OP2 interface, you can read large result files quickly and efficiently. For a more detailed list of features, see:. With Python 2 now officially dead, it's time for a new killer feature to get the last few people to switch. There is now support for writing OP2 files! They're difficult to create from scratch, but modifying an existing one isn't difficult.

This includes geometry support. Many bug fixes and a few more details on features, can be found in the. I keep saying to myself there's not much to add, but Nastran is huge. Beyond HDF5 support in the BDF, I'm a huge fan of the new ability to keep track of which include file a card came from and write it as a separate file.

It's limited in usefulness, but very handy in certain cases. There's a new still preliminary superelement capability. I'm far from a superelement expert, but it's probably useful.

Regarding the GUI, there are also some new features. Groups work a bit better, but aren't quite perfect. Logging has been dramatically sped up so the GUI loads faster and you can load Nastran models even faster if you disable additional results e.

Finally, Python 2. Numpy, scipy, and matplotlib have all dropped Python 2.
