how to write 3d lattice in openmc

Hi
I am facing problem in writting 3 dimensional array.How to write in xml??

Hi Kirti,

I recommend using python API to create the model (https://docs.openmc.org/en/v0.11.0/usersguide/install.html#). In the examples you can find how to do that array (https://docs.openmc.org/en/v0.11.0/examples/pandas-dataframes.html).

Hope this helps,
Javier
