Here we list the Summer of Code projects

2017

This summer I got to be a part of the JuliaFEM project. My main responsibilities where to code two repositories: NodeNumbering.jl and ModelReduction.jl. I also wrote a paper about calculating natural frequencies with JuliaFEM and improved the documentation and examples of JuliaFEM.

NodeNumbering.jl contains functions to perform the Reverse Cuthill-McKee algorithm which is used to reduce the bandwidth of sparse matrices. At the moment the package has 8 merged functions. The figure below shows how matrix bandwidth is reduced with the code.

ModelReduction.jl is a repository to reduce the dimension of a model for multibody dynamics problems. The package includes e.g. the Guyan reduction and the Craig-Bampton method. The package has 6 merged functions.

This summer I got great guidance from Tero and Jukka who taught me a lot. I learned how to use Github properly and how to perform the whole coding process with the right working methods. My coding skills progressed significantly and I learned a whole new coding language.

I am very happy that I got to be a contributor in the JuliaFEM project and I will definitely be a part of the JuliaFEM team also in the future and keep developing and improving it to be the best open source FEM solver in the world.
