Task 14: iterative Weight Windows via Python API - 4_sphere_iterative_per_batch_ww

[alanottrenfusion]

Hey guys !
I just encountered a problem with the "Task 14: iterative Weight Windows via Python API - 4_sphere_iterative_per_batch_ww" update_magic(ww_tally) process.
It seems using the openmc 014, the whole task is running perfectly. (the 2 calculations are about 1 minute)
I updated to the openmc 015, the calculation update_magic blocked in the second batch with no specific message.

Thanks for bringing this up.
We might have to look at openmc release notes and api changes to solve this one.
I shall see if I can reproduce this

Oh just to mention the workshop is tested on the develop branch of openmc. Might have more luck using that instead of version 0.15.

Hi ! Thanks for your reply.
Do you mean here: https://github.com/openmc-dev/openmc/tree/develop/tests
I can't find it. Maybe in another placeholder ?

[shimwell]

I mean we run CI on this neutronics-workshop repo and in that CI we use the openmc current develop branch which is currently 59 commits ahead of version 0.15. So it might be worth trying the develop branch of openmc which is the version in the neutronics-workshop docker file

Thanks ! i will try it out ! : )
I got back to the openmc 0.14 to use the magic feature and perform efficient calculation. It works for now.
Is it possible to install the dev version with conda/mamba or with spack ?
Thanks a lot for your help !

[shimwell]

conda / mamba only has released versions distributed, so no develop version there https://anaconda.org/conda-forge/openmc/files

I am not sure about spack but here is a link to the install docs for openmc which might contain more info

Hi Mr Shimwell,
i finaly got openmc v0.15.1 installed from source:

openmc --version

but it leads to the same results => when excecuting the loop with update_magic, the run get stuck in batch number 2:

Do you have any idea where this beviour can come from ?

[jon-proximafusion]

I've just run this task within the docker container and it appears to work fine for me.

Did you change anything in the task?

If not then I guess there is a difference between the environment in the docker container and your system.

You can take a peak at the docker files to see how I have installed things and perhaps there is a difference somewhere
