Dear Paul, Further to our discussion here i am currently working on converting the damage-energy score in [ev/source] to [displacement/sec]. Firstly, I am not very clear on how this tallied score in [ev/source] could be converted to [ev/sec]. As suggested by you here , i will be required to find the…

Dear Patrick, Thanks for the example. Will look in to that. Kind regards, Arun

Dear Patrick, I tried running your code and received the following error. I guess the openMC execution throws up this error while writing the ‘summary.h5’ file. The first execution of OpenMC proceeded without any errors. Probably you might’ve some suggestions. /home/ir-bala2/.local/lib/python3.7/s…

Thanks for posting. It looks like a summary file already exists (perhaps from a previous run) a quick fix would be to delete it before running. notebook terminal command using ! !rm summary.h5 or python old method import os os.system('rm summary.h5' or newer python import subprocess subproces…

@abarun , I hope Jon’s suggestion got you farther along. I just wanted to add a little bit to the discussion. My guess is that this error is occurring due to an open openmc.StatePoint object on your system in a Python interpreter. These objects claim the file handle of the HDF5 statepoint file (stat…

Dear Jon & Patrick, Thanks for the suggestions. Both of them worked well. Moving forward i will need to estimate the rate of swelling in my component model influenced by the DPA and the irradiation temperature. Look here for a brief introduction of the work i am currently associated with. The heat …

@abarun when you tally heating over a spatial region, OpenMC is giving you the integrated quantity, which doesn’t include any information on the spatial dependence across that region. If you have the heating tallied in many regions, it would be up to you to come up with a continuous representation t…

Dear Patrick, When I frist use openmc in Linux,I meet a probleme. It appears " RuntimeError: Failed to open HDF5 file with mode ‘r’ ". I hope you can help me.Thanke you for me. Wangkailong

This error is discussed in a separate thread: [image] Run-time error when I run openmc User Support Dear getlemen and women: When I use openmc to use a example ,I meet a RuntimeError. See the picture below for details. Thank you for helping me. [1667464695684]

Dear Shimwell, Thanks for this DPA example. Currently I am trying to adapt this code to be able to work with a dagmc based geometry. The inclusion of following line will infact impact the code relating to creation of tally filter and volume calculation. openmc.DAGMCUniverse(filename='dagmc.h5m') …

There are a few DAGMC with Openmc examples available for you. They tend to do different tallies to DPA so you will have to transfer your DPA tally skills to this new geometry type. I tend to perform tallies using cellFilter in CSG mode but switch to materialFilters for DAGMC The DAGMC geometry can…
