With **Trixi2Vtk.jl** you can convert the HDF5-based output files created by

[Trixi.jl](https://github.com/trixi-framework/Trixi.jl) (solution or restart

files) to VTK files. The converted files can then be further processed with

[ParaView](https://www.paraview.org) or [VisIt](https://visit.llnl.gov) to

generate publication-quality visualizations. Trixi2Vtk is part of the

[Trixi framework](https://github.com/trixi-framework).

## Installation

If you have not yet installed Julia, please [follow the instructions for your

operating system](https://julialang.org/downloads/platform/). Trixi2Vtk works

with Julia v1.10 and newer.

Trixi2Vtk is a registered Julia package. Hence, you can install it by executing

the following commands in the Julia REPL:

```julia

julia> import Pkg; Pkg.add("Trixi2Vtk")

```

To update an existing installation of Trixi2Vtk to the

[latest release](https://github.com/trixi-framework/Trixi2Vtk.jl/releases/latest),

execute

```julia

julia> import Pkg; Pkg.update("Trixi2Vtk"); Pkg.status("Trixi2Vtk")

```

in the Julia REPL. A brief list of notable changes to Trixi2Vtk is available in

[`NEWS.md`](NEWS.md).

## Usage

In the Julia REPL, first load the package Trixi2Vtk

```julia

julia> using Trixi2Vtk

```

To process an HDF5 file generated by Trixi.jl, execute

```julia

julia> trixi2vtk(joinpath("out", "solution_000000.h5"), output_directory="out")

```

This will create two unstructured VTK files in the `out/` subdirectory that can

be opened with ParaView or VisIt: `solution_000000.vtu` contains the

discontinuous Galerkin solution data while `solution_000000_celldata.vtu` holds

any cell-based values such as the current AMR indicator or the cell refinement

level.
