How we can use FEMTISE package ?

1. Clone FEMTISE package

First we need to clone package from GitHub repository as follow

    @prompt$: cd ~/my_directory/
    @my_directory$: git clone https://github.com/mendzmartin/FEMTISE.jl.git

This will download a folder called FEMTISE.jl, it is important to keep the .jl extension in the repository name. And, in case we have already cloned the repository, we must update it by running git pull.

2. Build Julia code to use FEMTISE package

    @prompt$: mkdir ~/my_folder
    @prompt$: cd ~/my_folder
    @my_folder$: julia

    julia> Ctrl+]
    (@v1.9) pkg>
    (@v1.9) pkg> activate .
    (@my_folder) pkg> instantiate
    (@my_folder) pkg> dev ~/my_directory/FEMTISE.jl
    julia> exit()

then build Julia code with following structure:

module MyModule

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

using FEMTISE

#=
... ...
    code block where we use function
    from FEMTISE package
... ....
=#

end

Then we save de Julia code below name MyModule.jl. After that, we can run the code doing this

    @my_directory$: julia MyModule.jl

Also, if we have activated multi-thread configuration we can use the next command to activate parallelism:

    @my_directory$: julia -t 4 MyModule.jl

where we have specified 4 threads as parallelization.

Run from Julia REPL

We can also run the package directly from Julia REPL by opening the terminal Ctrl+Alt+T inside the package folder and typing the following commands inside the terminal:

    @prompt$: cd my_directory/FEMTISE.jl/
    @FEMTISE.jl$: julia
               _

   _ _   _| |_  __ _   |  Type "?" for help, "]?" for Pkg help.

    (@my_folder) pkg> dev ~/my_directory/FEMTISE.jl
    julia> using FEMTISE

and then we can, for example, access Julia's help mode to ask for specific package functions such as the following:

    julia> Shift+?
    help?> space_coord
    search: space_coord

    if dimension=="1D" ⇒ dom=(x₁,x₂); Δr=Δx; n=nx
    if dimension=="2d" ⇒ dom=(x₁,x₂,y₁,y₂); Δr=(Δx,Δy); n=(nx,ny)
