Hello everyone, I am currently conducting a core calculation. The fuel rods in the core are arranged in a hexagonal matrix, and there is also a circle of pores around each fuel rod that are also arranged in a hexagonal pattern. The edges of the air holes around each fuel rod overlap. Now there are several questions:
How should this type of core modeling be carried out
2. During the modeling process, I divided a sub channel model for modeling. There are two hexagonal matrices, fuel rods and gas holes, in the model. How to fill them all into a hexagonal region and then put them into the root universe?
Thank you.
There is also a question about how to define a hexagonal arrangement of pores around the fuel rod using hexstrike, as the central fuel rod has already been set in the fuel rod matrix arrangement
