Elfel.jl: Extensible library for finite element methods

elfel<br> 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 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, MeshSteward.

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().
