How this geometry can be modeled in openMC

Hello everyone,

I need help in making geometry of a flux trap whose image is attached.
Can it be formed with x,y planes and z-cylinder or there can be any other way of modeling it?

Yes, you’d need four y-planes, four z-cylinders, and (less obviously) two x-planes that are used to create union regions for each of the two cells. I’ve attached a quick Python script that takes advantage of the OpenMC Python API in the latest develop branch along with the plot and geometry.xml file that it produces. Note that for a real model, you’d probably want to put real materials in the cells instead of having them be void.
