openmc-plot-mesh-tally is showing wrong image

Hello, I have a design where my fuel pin is 7.7 and 8.1 and 60 cm in x and y and z-direction. I am trying to get the fission reaction rate for each of the fuel pin with the below code. I have graphite radial reflector and in total of 42 assemblies.

<?xml version=**'1.0' **encoding=**'utf-8'**?>

<mesh id**=“1”>**

regular

7 6 1

<lower_left> -26.95 -24.3 -30.0 </lower_left>

7.7 8.1 60.0

<filter id**=“1” type=“mesh”>**

1

<tally id**=“1” name=“reaction”>**

1

total

After the project build when I run openmc-plot-mesh-tally statepoint.550.h5 I get the attached image, which is wrong cause i checked with the tallies.out file data I see the date are not mached with the color. the second image is what i am supposed to get. see the talliesreaction.out file. Please help.

Hi Sharif,

We had another user report a problem with openmc-plot-mesh-tally, so there might very well be a bug in it. For the time being, I would recommend using the Python API directly along with the statepoint file to generate these types of plots. We will look into the openmc-plot-mesh-tally script further to see what’s going wrong and let you know what we find.

Best regards,
Paul
