How to open, run and see results form .jl file

I have installed Julia and Pluto. Now I’d like to open .jl files, run those files and see results. Files are from [GitHub - vinhphunguyen/MPM-Julia: Julia implementation of the material point method (MPM)] (ResearchGate). Unfortunately I’m not a programmer and I don’t know how to do that. Could you help me please.

Depending on which one you want to run try:

include("<dir>/Main.jl")

Replacing <dir> with the one you want to run, i.e. CPD_3D_T4_Cantilever, Classic_2D_2Disk, etc. However the readme says:

The code was written 2 years ago and thus not compatible to the current Julia version.

So I’m not sure what version of Julia you need to be running to be able to run them.

…and the last commit on the reader is over 1 year old.

Note that nowadays a project (like in this case the code accompanying a paper) should be shipped with a Project/Manifest file so that anyone can have the exact Julia environment of the author (and hence replicate the results) by just typing ] activate . in the Julia prompt…
