Using taichi's legacy mls-mpm method for fast fluid sim.

## Install

Requirements: python3.5, python3.6, or python3.7 (3.8 and 3.9 do not work)

The following instructions pulled from: https://taichi.readthedocs.io/en/stable/legacy_installation.html

I'll assume you're using python3.7. Oh, and also I was unable to get this dumb thing working through pyenv either.

This is how you install the taichi legacy library. It'll compile the thing from source. (I recommend you put `install.py` in your home directory)

```shell

python3.7 -m pip install colorama numpy Pillow flask scipy pybind11 flask_cors GitPython yapf distro requests PyQt5 psutil

wget https://raw.githubusercontent.com/yuanming-hu/taichi/legacy/install.py

python3.7 install.py

```

Restart your shell (or `source ~/.bashrc`). Then install the fluid library https://github.com/yuanming-hu/taichi_mpm

```shell

ti install mpm

```

## Running

You can verify the install by running an example script.

```shell

python3.7 layersim3d_factory.py configs/test1.yaml

```

The output should look like:

```

```

## Output

The outputs will be stored in the taichi legacy source folder. (the same place you ran the `install.py` script). For me:

`~/taichi/outputs/mpm/`

The output data is in the `frames/*.bgeo` files. You can visualize them using [Houdini Apprentice](https://www.sidefx.com/products/houdini-apprentice/)
