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.

Hi Sharif,

Looking at your geometry XML, it looks like you should be able to see three different UO2 regions. Can you attach a resulting plot image and/or the complete model you have?

Best regards,
