'unable to open object (power doesn't exist)

Basically i’m trying to get graphs from a ‘depletion_results.h5’ file. the file i downlaoded off my uni computer where i’m running openmc to create the files and then using my own computer to get the graph. does anyone know how i can fix this

Hi @hhhnain. This probably occurred because the format of the depletion results file recently changed. The power data set was renamed to source_rate. If you update OpenMC on your own computer, it should be able to read the new format of the depletion results file.

how would i do that? i am using ubuntu

Just install an older version of openmc perhaps 0.12.0 or 0.11.0 by conda package manager.

conda create -n openmc_old python=3.8 -y
conda activate openmc_old
conda install openmc -c conda-forge openmc=0.12.0 -y
