Tutorials

There are a number of tutorials explaining the use of this package. Check out the index. The are tutorials themselves can be executed as follows:

• Download the package or clone it.

git clone https://github.com/PetrKryslUCSD/FinEtoolsAcoustics.jl.git

• Change into the tutorials folder: cd .\FinEtoolsAcoustics.jl\tutorials.
• Start Julia: julia.
• Activate the environment:

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

• Execute the desired tutorial. Here name_tut.jl is the name of the tutorial file:

include("name_tut.jl")

Examples

The examples have their own environment. Change the folder to examples. Then activate and instantiate the examples environment.

(FinEtoolsHeatDiff) pkg>

shell> cd examples
C:\Users\...\FinEtoolsHeatDiff.jl\examples

julia> using Pkg

julia> Pkg.activate("."); Pkg.instantiate()
  Activating project at `C:\Users\...\FinEtoolsHeatDiff.jl\examples`
   [Output suppressed...]

julia>

There are a number of examples, which may be executed as described in the conceptual guide to FinEtools. For instance

julia> include("steady_state/2-d\\Poisson_examples.jl"); Poisson_examples.allrun()
