How to creat mesh for a hexagonal assembly?

Dears:

I apologize in advance if my question comes as naive.

I am newbie for using OpenMC. I want to creat mesh of hexagonal assembly for tally mesh filter. And this is only a simple way for reactangle assembly in the example guide.

Thanks a lot.

Hi @lei and apologies for the slow response here. Right now we do not have any hexagonal mesh capability in OpenMC. However, if you have a cell that is repeated within that hexagonal assembly, you can use a DistribcellFilter to get a tally for each instance of the cell that appears within the assembly.

so we can’t get flux distribution using hexagonal pitch ike this example Post Processing — OpenMC Documentation ?

Correct, there is no hexagonal equivalent of the example shown in that post processing section.

is there any other way to get flux distribution with hexagonal pitch?

As I suggested before, using the DistribcellFilter allows you to tally each instance of a cell that is repeated within a hexagonal lattice. However, there is no simple way to visualize the results of that tally at present.
