# pyXDSM

A python library for generating publication quality PDF XDSM diagrams.
This library is a thin wrapper that uses the TIKZ library and LaTeX to build the PDFs.

# Installation
Clone this repo or download the zip and unzip it.

    cd pyxdsm
    pip install .

## What is XDSM?
The eXtended Design Struture Matrix (XDSM) is a graphical language for describing the movement of data and the execution sequence for a  multidisciplinary optimization  problem.
You can read the [paper by Lambe and Martins](http://mdolab.engin.umich.edu/content/extensions-design-structure-matrix) for all the details.
If you  would like a citation for XDSM, here is the bibtex for that paper:

    @article {Lambe2012,
    title = {Extensions to the Design Structure Matrix for the Description of Multidisciplinary Design, Analysis, and Optimization Processes},
    journal = {Structural and Multidisciplinary Optimization},
    volume = {46},
    year = {2012},
    pages = {273-284},
    doi = {10.1007/s00158-012-0763-y},
    author = {Andrew B. Lambe and Joaquim R. R. A. Martins}
    }


## TIKZ and LaTeX?
You need to install these libraries for pyXDSM to work. See the [install guide](https://www.latex-project.org/get/) for your platform

## How do I use it?
Here is a simple example. There are some other more advanced things you can do as well. Check out the [examples folder](https://github.com/mdolab/pyXDSM/blob/master/examples)
```python
from pyxdsm.XDSM import XDSM

#
opt = 'Optimization'
solver = 'MDA'
comp = 'Analysis'
group = 'Metamodel'
func = 'Function'

x = XDSM()

x.add_system('opt', opt, r'\text{Optimizer}')
x.add_system('solver', solver, r'\text{Newton}')
x.add_system('D1', comp, r'D_1')
x.add_system('D2', comp, r'D_2')
x.add_system('F', func, r'F')
x.add_system('G', func, r'G')


x.connect('opt', 'D1', r'x, z')
x.connect('opt', 'D2', r'z')
x.connect('opt', 'F', r'x, z')
x.connect('solver', 'D1', r'y_2')
x.connect('solver', 'D2', r'y_1')
x.connect('D1', 'solver', r'\mathcal{R}(y_1)')
x.connect('solver', 'F', r'y_1, y_2')
x.connect('D2', 'solver', r'\mathcal{R}(y_2)')
x.connect('solver', 'G', r'y_1, y_2')


x.connect('F', 'opt', r'f')
x.connect('G', 'opt', r'g')

x.add_output('opt', r'x^*, z^*', side='left')
x.add_output('D1', r'y_1^*', side='left')
x.add_output('D2', r'y_2^*', side='left')
x.add_output('F', r'f^*', side='left')
x.add_output('G', r'g^*', side='left')
x.write('mdf')
```

This will output `mdf.tex`, a standalone tex document that (by default) is also compiled to `mdf.pdf`.

## More complicated example

Here is an example that uses a whole bunch of the more advanced features in pyXDSM. Its mostly just a reference for all the customizations you can do.
The code for this is in the [examples folder](https://github.com/mdolab/pyXDSM/blob/master/examples/kitchen_sink.py)

## Embedding the diagram directly in LaTeX

In addition, the file, `mdf.tikz`, can be embedded in another tex file using
the `\input` command:

```
\begin{figure}
  \caption{Example of an MDF XDSM.}
  \centering
  \input{mdf.tikz}
  \label{fig:xdsm}
\end{figure}
```

The following is required to be in the preamble of the document:

```
\usepackage{geometry}
\usepackage{amsfonts}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{tikz}

\usetikzlibrary{arrows,chains,positioning,scopes,shapes.geometric,shapes.misc,shadows}
```
