Greetings everyone !
i have tried to calculate the RBMK burnout, but something went wrong
as i see, materials and geometry files are just normal, but something went wrong
OPENMC v 13.2
Ubuntu 22.04 lts

ERROR: Something went wrong reading coeffs for surface 1
application called MPI_Abort(MPI_COMM_WORLD, -1) - process 0
[unset]: write_line error; fd=-1 buf=:cmd=abort exitcode=-1
:
system msg for write_line failure : Bad file descriptor
Restarting kernel…
also - surface 1 from geometry.xml
surface coeffs=“0.0 0.0 0.58” id=“1” type=“z-cylinder”
also, encountered this situation just before the coeffs problem:
But solved it by defining density in kg/m3 instead of g/cm3
Update - Just tried to calculate old problem, that was prepared in v0.12 and worked good, but it failed with the same output, even in v.12
@morpork I tried running your model (both using the XML files as well as regenerating using the .py script) using version 0.13.2 and didn’t encounter any errors regarding the surface coefficients. I notice that you’re running this with MPI – one possible issue is that if you call mpiexec ... python RBMK.py, multiple MPI ranks might be trying to write the XML files simultaneously. You may want to remove the export_to_xml() calls from your script since the CoupledOperator class will handle that anyway.
Thank you for answer !
It looks, like spyder IDE, i am using last years, or something with it in conda is broken now.
i ve tried to run this program in pycharm with the same conda enviroment, and it works just fine.
so, problem is solved.
