# Elfel.jl: Extensible library for finite element methods

**elfel**


G. *adjective*. different, like something else, unique, unparalled

## Introduction

This package provides support for the development of Finite Element Method applications, especially in continuum mechanics. Mixed methods with cooperating finite element spaces are supported. High performance is one of the focus points. Check out the [tutorials](https://petrkryslucsd.github.io/Elfel.jl/dev/tutorials/tutorials.html#Tutorials) to get a feel for the functionality of this package.

## Dependencies

The library relies on mesh support from the following suite of small mesh-management packages: [`MeshCore`](https://github.com/PetrKryslUCSD/MeshCore.jl), [`MeshSteward`](https://github.com/PetrKryslUCSD/MeshSteward.jl).

## Usage

Clone the repository, and execute

```

using Pkg; Pkg.activate("."); Pkg.instantiate()

```

in the `Elfel` folder.

The user can either use/import individual functions from `Elfel` like so:

```

using Elfel.FElements: FEH1_T6, FEH1_T3, refshape, Jacobian

```

or all exported symbols maybe made available in the user's context as

```

using Elfel.Exports

```

The `examples` folder can be explored by simply running the files with `include()`.
