|
||
| 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. | ||

| - GitHub: <https://github.com/AppliedMechanics-EAFIT/SolidsPy> | ||
| - PyPI: <https://pypi.org/project/solidspy/> | ||
| - Free and open source software: [MIT license](http://en.wikipedia.org/wiki/MIT_License) | ||
|
|
||
| ## Features | ||
|
|
||
| - It is based on an open-source environment. | ||
| - 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. | ||
| - It has been used to tech the following courses: | ||
| - Introduction to Solid Mechanics. | ||
| - Computational Modeling. | ||
| - Introduction to the Finite Element Methods. | ||
| - Introduction to Soil Mechanics. | ||
|
|
||
| ## Installation | ||
|
|
||
| The code is written in Python and it depends on `numpy`, and `scipy` and. It | ||
| has been tested under Windows, Mac, Linux and Android. | ||
|
|
||
| To install *SolidsPy* open a terminal and type: | ||
|
|
||
| pip install solidspy | ||
|
|
||
| To specify through a GUI the folder where the input files are stored you will | ||
| need to install [easygui](http://easygui.readthedocs.org/en/master/). | ||
|
|
||
| To easily generate the required SolidsPy text files out of a | ||
| [Gmsh](http://gmsh.info/) model you will need [meshio](https://github.com/nschloe/meshio). | ||
|
|
||
| These two can be installed with: | ||
|
|
||
| pip install easygui | ||
| pip install meshio | ||
|
|
||
| ## How to run a simple model | ||
|
|
||
| For further explanation check the [docs](http://solidspy.readthedocs.io/en/latest/). | ||
|
|
||
| Let's suppose that we have a simple model represented by the following files | ||
| (see [tutorials/square example](http://solidspy.readthedocs.io/en/latest/tutorials/square_example.html) | ||
| for further explanation). | ||

|
|
||
|
|
||
| Run it in Python as follows: | ||
|
|
||
| ``` python | ||
| import matplotlib.pyplot as plt # load matplotlib | ||
| from solidspy import solids_GUI # import our package | ||
| disp = solids_GUI() # run the Finite Element Analysis | ||
| plt.show() # plot contours | ||
| ``` | ||
|
|
||
| For Mac users it is suggested to use an IPython console to run the example. | ||
