## Installation prerequisite
In principle, any Conda/Mamba distribution will work. A few Conda/Mamba options are:
- [Miniforge](https://github.com/conda-forge/miniforge#miniforge-pypy3) (recommended as it includes mamba)
- [Anaconda](https://www.anaconda.com/download)
- [Miniconda](https://docs.conda.io/en/latest/miniconda.html)
## Install using Mamba and pip
This example assumes you have installed the MiniForge option or separately
installed Mamba with ```conda install -c conda-forge mamba -y```
Create a new conda environment, I've chosen Python 3.10 here but newer versions should also work.
```bash
mamba create --name new_env python=3.10 -y
```
Activate the environment
```bash
mamba activate new_env
```
Install the dependencies, if this fails to solve the environment you could also try [installing OpenMC from source](https://docs.openmc.org/en/stable/quickinstall.html) which might be preferred.
```bash
mamba install -y -c conda-forge gmsh python-gmsh "openmc=dagmc*nompi*"
```
CadQuery should then be installed, here is the mamba command and the pip command.
```bash
mamba install -y -c conda-forge ocp cadquery
```
If the mamba command fails to solve the environment then try this pip command.
```bash
python -m pip install cadquery-ocp cadquery
```
Then you can install whichever convertor you want to test. The cad_to_dagmc and the CAD_to_OpenMC packages can both be installed with ```pip``` or ```conda```. **Warning** these should be installed in separate environments as they require a different version of Open Cascade.
```bash
python -m pip install cad_to_dagmc
```
or
```bash
python -m pip install CAD_to_OpenMC
```
Then you can install the model benchmark zoo with ```pip```
```bash
python -m pip install git+git://github.com/fusion-energy/model_benchmark_zoo.git
```
## Usage
Example scripts that make CSG and DAGMC geometry can be found in [the examples folder](https://github.com/fusion-energy/model_benchmark_zoo/tree/main/examples)
