Visualization of a Geometry with ParaView

Objective

I am creating a detector in OpenMC with the goal of running simulations. As a first step, I need to create the geometry and verify it in 3D using ParaView.

Steps

1. Create the Geometry

I write the geometry in my Python script.

2. Compile the Program

I run my script, which generates a file named plot_1.h5.

3. Convert the plot_1.h5 File to VTI Format

I use the following command to convert the plot_1.h5 file into a format that ParaView can read:

openmc-voxel-to-vtk plot_1.h5 -o geometry.vti

4. Open ParaView

I open ParaView and set some parameters according to this previous topic:
OpenMC Discourse - Geometry Plotting Issue

I still have issues with the visualization; I cannot see my geometry in the file as you can see with this image:

Could you please help me?

I am sending you the OpenMC modeling file attached. However, I am not able to send the plot_1.h5 and geometry.vti files.

Best regards,

I suggest to have a look at the following tutorial

However,
(a) It is a bit tedious to get a geometry to look good in paraview
(b) hence debugging a geometry with paraview does not sound as a good solution
