Hi guys, I know that openmc-0.13.0 has allowed us to use the cylindrical mesh for our model. And now I want to set the mesh on each pin of my model , but I dont know how to locate the origin of the mesh for each pin. I have read the source code of the mesh in user documentation , and did not find the information I want. Does cylindrical mesh allow us to use on each pin? * * * Best regard! Zhuangli ---

This question was answered in a separate topic: > [@About cylindrical mesh using in multi cylindrical-fuel pins](https://openmc.discourse.group/t/about-cylindrical-mesh-using-in-multi-cylindrical-fuel-pins/2027/2): > > If you wanted to have a cylindrical mesh in multiple fuel pins, you would need to define a separate mesh for each fuel pin. There is no way to have a single cylindrical mesh cover multiple fuel pins. Alternatively, the MeshFilter class allows you to arbitrarily translate the mesh being used, so if your goal is to just tally over multiple fuel pins with the same cylindrical mesh, you could do that with a single CylindricalMesh and multiple MeshFilters. This would look like: mesh = openmc.Cylind…
