Hello, I have a fuel pin with 3 fuel pellets and aluminum oxide upper and below cap. The pellet in the middle is 1cm height and 2 21cm pellets on top and bottom. Also, 1 6cm aluminum oxide cap in the top and 1 in the bottom. So the total height with the fuel pin is 55cm. As you can see I am defining the surface and cells below.
Now, I see the 3 fuel pellets is showing 1 in xz geometry plot. But I define separate cells for them. How can I show the cell lines in openMC?
Thanks.
