## Installation

```julia

# Type ] to enter package mode

pkg> add STLCutters

```

## Examples

### Sub-triangulation examples

Use a test geometry, e.g., `47076.stl` (Chichen Itza)

```julia

julia> include("examples/SubTriangulation.jl")

julia> filename = "test/data/47076.stl"

julia> SubTriangulation.main(filename,n=50,output="example1")

```

![Example 1](examples/example1.png)

Download a geometry directly from [Thingi10k](https://ten-thousand-models.appspot.com/), e.g, [37384](https://ten-thousand-models.appspot.com/detail.html?file_id=37384). Please check whether the geometry is *solid* and *manifold* in Thingi10k metadata.

```julia

julia> include("examples/SubTriangulation.jl")

julia> filename = SubTriangulation.download(37384)

julia> SubTriangulation.main(filename,n=50,output="example2")

```

![Example 2](examples/example2.png)

### Finite Elements examples

Solve a **Poisson** equation on a test geometry, e.g., `293137.stl` (Low-Poly Bunny)

 ```julia

julia> include("examples/Poisson.jl")

julia> filename = "test/data/293137.stl"

julia> Poisson.main(filename,n=20,output="example3")

```

![Example 3](examples/example3.png)

Solve a **Linear Elasticity** problem on a test geometry, e.g., `550964.stl` (Eiffel Tower in a 5 degree slope)

 ```julia

julia> include("examples/LinearElasticity.jl")

julia> filename = "test/data/550964.stl"

julia> LinearElasticity.main(filename,n=50,force=(tand(5),0,-1),output="example4")

```

![Example 4](examples/example4.png)

Solve an **Incompressible Flow** problem on a test geometry, e.g., `47076.stl` (Chichen Itza)

 ```julia

julia> # ENV["ENABLE_MKL"] = "" ## Uncomment if GridapPardiso.jl requirements are fulfilled

julia> include("examples/Stokes.jl")

julia> filename = "test/data/47076.stl"

julia> Stokes.main(filename,n=10,output="example5")

```
