Trixi2Img.jl

Note: This repository is not actively developed anymore. If you want to visualize simulation results created by Trixi.jl, please use another option such as Plots.jl, Makie.jl, or Paraview/Visit via Trixi2Vtk as described in the documentation of Trixi.jl.

Trixi2Img.jl can create PDF/PNG files from output files created by Trixi.jl (solution or restart files). Trixi2Img is part of the Trixi framework.

Installation

If you have not yet installed Julia, please follow the instructions for your operating system. Trixi2Img works with Julia v1.5.

Trixi2Img is a registered Julia package. Hence, you can install it by executing the following commands in the Julia REPL:

julia> import Pkg; Pkg.add("Trixi2Img")

Usage

In the Julia REPL, first load the package Trixi2Img

julia> using Trixi2Img

To process an HDF5 file generated by a 2D simulation with Trixi.jl, execute

julia> trixi2img(joinpath("out", "solution_000040.h5"), output_directory="out", grid_lines=true)

This will create a file solution_000040_scalar.png in the out/ subdirectory that can be opened with any image viewer:

To visualize 3D data generated by Trixi.jl, a 2D slice must be extracted. A slice can only lie in a plane orthogonal to one of the coordinate axes. The slice plane is defined by the axis to which it is orthogonal and an axis intercept.

For example, to create a 2D slice in the xy-plane at the axis intercept z = 0.5 from 3D data, execute

julia> trixi2img(joinpath("out", "solution_000000.h5"), output_directory="out", grid_lines=true, slice_axis=:z, slice_axis_intercept=0.5)

For further information on how to use Trixi with Trixi2Img, please refer to the documentation of Trixi.
