There was a problem hiding this comment.
Nice! I'm a little surprised the list took up that much space. Thanks for the clear improvement!

Another straightforward change from @paulromano so I don't let this one linger long either once tests pass. |

Description
I found that when trying to export unstructured mesh tally data to a VTK file using the
UnstructuredMesh.write_data_to_vtkmethod, it blew out the memory on my machine. After a little digging, I was able to attribute this to the fact that in that method, we're holding a list ofvtkTetraelements, which doesn't appear to be necessary. With this fix, the memory use is much lower.Checklist
I have run clang-format (version 15) on any C++ source files (if applicable)I have added tests that prove my fix is effective or that my feature works (if applicable)
