Hℹ guys, I use the cylindrical mesh to tally the fission rate and I want to see its distribution. Are there a method to get it ? Any help will be thanks! Best regards! Zhuangli

Hi @lz152 , I’ve been meaning to finish up a feature that will apply data (from a mesh tally) to any 3D mesh and write a VTK file from the Python API. It’s still in a working state, but if you’re up for working with a source installation, here’s the branch if you want to give it a try! GitH…

Hi Shriwise, Thank you. it is a nice code for cylindrical-mash-tally to get a visualization. I will try to use it! Anything else: Dose the cylindrical-mesh-tool available with a source installation? Best regards! ZhuangLi

No problem! Let me know how it goes! Dose the cylindrical-mesh-tool available with a source installation? If you do a source installation with that branch, cylindrical meshes will be available, yes. I hope I understood your question correctly.

Yeah. You are right! :joy: Thank you :+1:~

Hello @pshriwise , Sorry to revive this topic. The mesh filter documentation says that only regular, rectangular meshes can be used together with the mesh filter. And i indeed found strange results while inadvertently using a cylindrical mesh in a mesh filter. I would like to ask if that is really t…

@Artur You should be able to use a cylindrical mesh in conjunction with the MeshFilter class. The documentation there should be updated so thanks for pointing that out! Feel free to elaborate on what you believe is strange about the results you’re seeing.

Noting here that the documentation on this class has now been updated in this PR thanks to @paulromano .

Hello @paulromano , I found strange results when trying to reproduce the radial power distribution on a simple pin cell model using a cylindrical mesh. I defined the cylindrical mesh tally as follows: cylindrical_mesh = openmc.CylindricalMesh() cylindrical_mesh.r_grid = np.linspace(0.0, fuel_outer_…

@Artur It looks like there may be a bug with cylindrical mesh tallies when the tracklength estimator is used. If you change the estimator to collision: T4.estimator = 'collision' and rerun your problem, you should see the correct behavior. I’ll try to do some digging on this to see if I can figure…

I have just rerun the simulation using the collision estimator and i got the correct results. Thank you very much for the help.
