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()

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()
