TrussTopOpt.jl

Truss topology optimization experiments using TopOpt.jl and JuAFEM.jl.

Installation

In Julia v1.0+ you can install packages from the Pkg REPL (press ] in the Julia REPL to enter pkg> mode):

pkg> add https://github.com/yijiangh/JuAFEM.jl.git
pkg> add https://github.com/yijiangh/Tensors.jl.git
pkg> add https://github.com/mohamed82008/VTKDataTypes.jl#master
pkg> add https://github.com/mohamed82008/KissThreading.jl#master
pkg> add https://github.com/yijiangh/TopOpt.jl#master
pkg> add https://github.com/yijiangh/TrussTopOpt.jl#master

which will track the master branch of the package. (we still need to use a fork of TopOpt.jl before these changes are merged.)

To load the package, use

using TrussTopOpt
