It is a Python package designed to handle the pre and postprocessing of
the high-order Navier-Stokes solver [XCompact3d](https://github.com/xcompact3d/Incompact3d). It aims to help users and
code developers to build case-specific solutions with a set of tools and
automated processes.

The physical and computational parameters are built on top of [traitlets](https://traitlets.readthedocs.io/en/stable/index.html),
a framework that lets Python classes have attributes with type checking, dynamically calculated default values, and ‘on change’ callbacks.
In addition to [ipywidgets](https://ipywidgets.readthedocs.io/en/latest/) for an user friendly interface.

Data structure is provided by [xarray](https://docs.xarray.dev/en/stable) (see [Why xarray?](https://docs.xarray.dev/en/stable/getting-started-guide/why-xarray.html)), that introduces labels in the form of dimensions, coordinates and attributes on top of raw [NumPy](https://numpy.org/)-like arrays, which allows for a more intuitive, more concise, and less error-prone developer experience. It integrates tightly with [dask](https://dask.org/) for parallel computing and [hvplot](https://hvplot.holoviz.org/user_guide/Gridded_Data.html) for interactive data visualization.

Finally, Xcompact3d-toolbox is fully integrated with the new *Sandbox Flow Configuration*.
The idea is to easily provide everything that XCompact3d needs from a [Jupyter Notebook](https://jupyter.org/), like initial conditions, solid geometry, boundary conditions, and the parameters.
It makes life easier for beginners, that can run any new flow configuration without worrying about Fortran and [2decomp](http://www.2decomp.org/).
For developers, it works as a rapid prototyping tool, to test concepts and then compare results to validate any future Fortran implementation.

## Installation

It is possible to install using pip:

```bash
pip install xcompact3d-toolbox
```

There are other dependency sets for extra functionality:

```bash
pip install xcompact3d-toolbox[visu] # interactive visualization with hvplot and others
```

To install from source, clone de repository:

```bash
git clone https://github.com/fschuch/xcompact3d_toolbox.git
```

And then install it interactively with pip:

```bash
cd xcompact3d_toolbox
pip install -e .
```

You can install additional dependencies as well:

```bash
pip install -e .[visu]
```

Now, any change you make at the source code will be available at your local installation, with no need to reinstall the package every time.

## Examples

- Importing the package:

  ```python
  import xcompact3d_toolbox as x3d
  ```

- Loading the parameters file (both `.i3d` and `.prm` are supported, see [#7](https://github.com/fschuch/xcompact3d_toolbox/issues/7)) from the disc:

  ```python
  prm = x3d.Parameters(loadfile="input.i3d")
  prm = x3d.Parameters(loadfile="incompact3d.prm")
  ```

- Specifying how the binary fields from your simulations are named, for instance:

- If the simulated fields are named like `ux-000.bin`:

  ```python
  prm.dataset.filename_properties.set(
     separator = "-",
     file_extension = ".bin",
     number_of_digits = 3
  )
  ```

- If the simulated fields are named like `ux0000`:

  ```python
  prm.dataset.filename_properties.set(
     separator = "",
     file_extension = "",
     number_of_digits = 4
  )
  ```

- There are many ways to load the arrays produced by your numerical simulation, so you can choose what best suits your post-processing application.
  All arrays are wrapped into [xarray](http://docs.xarray.dev/en/stable) objects, with many useful methods for indexing, comparisons, reshaping and reorganizing, computations and plotting.
  See the examples:

- Load one array from the disc:

  ```python
  ux = prm.dataset.load_array("ux-0000.bin")
  ```

- Load the entire time series for a given variable:

  ```python
  ux = prm.dataset["ux"]
  ```

- Load all variables from a given snapshot:

  ```python
  snapshot = prm.dataset[10]
  ```

- Loop through all snapshots, loading them one by one:

  ```python
  for ds in prm.dataset:
     # compute something
     vort = ds.uy.x3d.first_derivative("x") - ds.ux.x3d.first_derivative("y")
     # write the results to the disc
     prm.dataset.write(data = vort, file_prefix = "w3")
  ```

- Or simply load all snapshots at once (if you have enough memory):

  ```python
  ds = prm.dataset[:]
  ```

- It is possible to produce a new xdmf file, so all data can be visualized on any external tool:

- Loop through all snapshots, loading them one by one:

- User interface for the parameters with IPywidgets:

  ```python
  ds = prm.dataset[:]
  ```

- It is possible to produce a new xdmf file, so all data can be visualized on any external tool:

  ```python
  prm.dataset.write_xdmf()
  ```

- User interface for the parameters with IPywidgets:

  ```python
  prm = x3d.ParametersGui()
  prm
  ```
