Added simple code snippets to
LoadSimfor identifying athena++ vtk files and read them. Users can useload_vtkto read the data. It returns a dictionary containing arrays x1f, x2f, x3f, and other field variables. It works for both uniform grids and AMR data. The shape of x1f is (nmb, nx1_mb), field_var (nmb, nx1_mb, nx2_mb, nx3_mb). I have not tested for joined vtk files.In its current form it's not very much useful. We can make it more useful by adding an option for converting to an xarray DataSet (especially for uniform grids data or data with a few levels of refinement). We can also improve the vanilla athena++ vtk reader (currently it doesn't even read the output time).
However, unless there are advantages of using vtk output (possibly as tarred format?) over hdf5 with athena++, it will not be worth putting much effort to improve this.
