Finite Element Analysis Library in Python

FEALPy: Finite Element Analysis Library in Python

We want to develop an efficient and easy to use finite element software package to support our teach and research work.

We still have lot work to do.

Install

Ubuntu

1. please install the python envieronment.

$ sudo apt install git            # The version control tool
$ sudo apt install python3        # The python3 interpretor 
$ sudo apt install python3-pip    # The PyPA recommended tool for installing Python packages.
$ sudo apt install python3-tk     # Python interface to Tcl/Tk used by matplotlib 

2. clone the latest fealpy from github or gitlab:

$ git clone https://github.com/weihuayi/fealpy.git

or

$ git clone https://gitlab.com/weihuayi/fealpy.git

3. In fealpy/, run the following command:

$ python3 setup_linux.py install --prefix=~/.local

which will copy the fealpy into ~/.local/lib/python3.<x>/site-packages/. Or run the following command:

$ python3 setup_linux.py develop --prefix=~/.local

which will create a soft link in ~/.local/lib/python3.<x>/site-packages/. 4.

$ pip3 install -U vtk
$ pip3 install -U meshio

Windows: Anaconda

1. Download and install latest Anaconda for Windows. https://www.anaconda.com/distribution/
2. Download and insall latest Git for Windows, https://gitforwindows.org/
3. Open Anaconda Powershell Prompt (Anaconda3) from start menu, and config your name and email information for git.

> git config --global user.name "Your Name"
> git config --global user.email "Your Email"

4. Then clone the latest fealpy

> cd Desktop
> mkdir git # create a directory named git. Of course, you can name it by another name you like.
> cd git # enter git directory
> git clone https://github.com/weihuayi/fealpy.git # clone the fealpy repo

or

> git clone https://gitlab.com/weihuayi/fealpy.git # clone the fealpy repo

5. enter fealpy directory, run the following command:

> python setup_win.py develop 
> pip install https://download.lfd.uci.edu/pythonlibs/s2jqpv5t/MeshPy-2018.2.1-cp37-cp37m-win_amd64.whl
> pip install https://download.lfd.uci.edu/pythonlibs/s2jqpv5t/pyamg-4.0.0-cp37-cp37m-win_amd64.whl
> conda install -c anaconda vtk 

Notice that, the above whl files are build for python3.7, you can find suitable version for other python version.

Mac

1. Download and install latest Anaconda for macOS. https://www.anaconda.com/distribution/
2. Download and insall latest Git for Mac, https://git-scm.com/download/mac.
3. Open command terminal and config your name and email information for git.

$ git config --global user.name "Your Name"
$ git config --global user.email "Your Email"

4. Then clone the latest fealpy

$ cd ~ # enter your home directory 
$ mkdir git # create a directory named git. Of course, you can name it by another name you like.
$ cd git # enter git directory
$ git clone https://github.com/weihuayi/fealpy.git # clone the fealpy repo

or

$ git clone https://gitlab.com/weihuayi/fealpy.git # clone the fealpy repo

5. enter fealpy directory, run the following command:

$ python setup_mac.py develop 
$ conda install -c anaconda vtk

Debug in python

sudo apt-get install python3-dbg

Debug python program:

$ gdb python3
...
(gdb) run <programname>.py <arguments>
