Error depletion analysis

Hello everyone,

I have some issues in my depletion analysis. I tried the ENDF/B-VII.1 and ENDF/B-VIII.0 each one with the casl, endfb71 and endfb71_fast depletion chains. In all cases, I get the same error after the first transport simulation. This is the information appearing after the first transport simulation (also shown in attached figure):

Hi all,

Please, can anyone help me with the issue above described? I don’t understand what is happening, I appreciate any idea.

Hi Javier,

I can’t really tell without your input files, but it looks like you might be trying to write the state file to the root directory where you don’t have permissions.

If you have manually set the location of the statefile, try to remove that setting and let openmc put it in the directory where you are running the simulation (assuming you have write privileges at that location). Otherwise change the directory of the state file to a location in your home folder where you have write privileges.

Hope this helps.

Hi Hunter,

Thanks for your response. I checked and it seems I have all privileges. I sent you the input files, if you can take a look I appreciate.

Javier,

Can you explain what you mean by “I have all privileges.” Are you able to create an file in the root directory with something like “touch /statepoint.txt” without invoking sudo. This will make an empty file in the root directory as an unprivileged user, near where you / openmc was attempting to make the statepoint file.

Drew

It tuns out the issue that Javier was experiencing was due to a bug in OpenMC, identified and fixed here.

Hi Andrew,

Thanks for your answer. Paul helped me with this and my simulation is running.
