Desktop, press `Ctrl+Shift+O`. +# - In the opened window, paste `trixi-framework/Trixi.jl` and choose the path to the folder where +# you want to save Trixi.jl. Then click `Clone` and Trixi.jl will be cloned to your computer. + +# Now you cloned Trixi.jl and only need to tell Julia to use the local clone as the package sources: +# - Open a terminal using `Win+r` and `cmd`.

After we used the +# `solve` function with [`SaveSolutionCallback`](@ref) there is a file with the final solution. +# It is located in the `out` folder and is named as follows: `solution_index.h5`. The `index` +# is the final time step of the solution that is padded to 6 digits with zeros from the beginning. +# With [Trixi2Vtk](@ref) you can convert the HDF5 output file generated by Trixi.jl into a VTK file. +# This can be used in visualization tools such as [ParaView](https://www.paraview.org) or +# [VisIt](https://visit.llnl.gov) to plot the solution. The important thing is that currently +# Trixi2Vtk.jl supports conversion only for solutions in 2D and 3D spatial domains. + +# If you haven't added Trixi2Vtk.jl to your project yet, you can add it as follows. +# ```julia +# import Pkg +# Pkg.add(["Trixi2Vtk"]) +# ``` +# Now we load the Trixi2Vtk.jl package and convert the file `out/solution_000018.h5` with +# the final solution using the [`trixi2vtk`](@ref) function saving the resulting file in the +# `out` folder. + +using Trixi2Vtk +trixi2vtk(joinpath("out", "solution_000018.h5"), output_directory="out") + +# Now two files `solution_000018.vtu` and `solution_000018_celldata.vtu` have been generated in the +# `out` folder. The first one contains all the information for visualizing the solution, the +# second one contains all the cell-based or discretization-based information. + +# Now let's visualize the solution from the generated files in ParaView. Follow this short +# instruction to get the visualization. +# - Download, install and open [ParaView](https://www.paraview.org/download/). +# - Press `Ctrl+O` and select the generated files `solution_000018.vtu` and +# `solution_000018_celldata.vtu` from the `out` folder. +# - In the upper-left corner in the Pipeline Browser window, left-click on the eye-icon near +# `solution_000018.vtu`. +# - In the lower-left corner in the Properties window, change the Coloring from Solid Color to +# scalar. This already generates the visualization of the final solution. +# - Now let's add the mesh to the visualization. In the upper-left corner in the +# Pipeline Browser window, left-click on the eye-icon near `solution_000018_celldata.vtu`. +# - In the lower-left corner in the Properties window, change the Representation from Surface +# to Wireframe.
