Non-rectangular nor hexagonal lattice

User Support

Hi everyone,

I have an issue to define a lattice for MTR fuel element which in some cases has a curved lattice. I tried to make the fuel cell as curved and it worked while I am trying to do a curved lattice which I couldn’t find a suitable function for it because all the provided either rectangular or hexagonal.

Is there any function can do a curved lattice as shown in drawing below?

I am asking this because I saw it in MCNP, as pecture below:

Also, this is will be very helpful in case of curved fuel plates, it will help the users to create a fuel element by defining one fuel plate and repeat it with it the universe of the fuel element without creates many surfaces to define the plates.

Best Regards,
Alaa
