Acoustic wave scattering on a gingerbread man

The files in this folder can be used to reproduce the numerical experiment simulating acoustic wave scattering on a gingerbread man mesh with Trixi.jl. The provided control file mesh_gingerbread_man.control is used by HOHQMesh.jl to generate the unstrucutred quad mesh file for this simulation. Once generated, the mesh file mesh_gingerbread_man.mesh is placed in the out folder. All results were obtained with Julia v1.6.2 on a computer running macOS Big Sur 11.5.

To reproduce the numerical experiments and the figure shown in the paper, proceed as follows.

  • Start Julia in this folder and activate the project environment therein (e.g., julia --project=. in this folder). Pass the command line option --check-bounds=no to increase the runtime performance. You can also use multithreading by passing the command line option --threads=XXX to Julia.
  • Execute the following code in Julia. 
    julia> using Trixi

julia> trixi_include("elixir_ape_gingerbread_man.jl", tspan=(0.0, 8.0))

julia> trixi_include("elixir_ape_gingerbread_man.jl", tspan=(0.0, 16.0))

This will produce the necessary .vtu plot files that can be opened with ParaView to visualize the solution.
