Bug Description
@rossmacdonald98 and I recently noticed negative values in a tally with a CylindricalMesh filter.
Also discussed this with @pshriwise
Code available here
Tally
ID = 1
Name = TBR
Filters = CellFilter, MeshFilter
Nuclides = total
Scores = ['(n,Xt)']
Estimator = tracklength
Multiply dens. = True
No. radial bins (x) 28
No. angular bins (y) 2
No. axial bins (z) 26
Dataframe:
cell mesh 1 nuclide score mean std. dev.
x y z
0 7 1 1 1 total (n,Xt) 4.66e-07 1.20e-07
1 7 2 1 1 total (n,Xt) -1.60e-04 1.52e-04
2 7 3 1 1 total (n,Xt) -5.71e-06 1.50e-05
3 7 4 1 1 total (n,Xt) -2.46e-05 2.86e-05
4 7 5 1 1 total (n,Xt) -7.69e-05 8.44e-05
... ... ... .. .. ... ... ... ...
1451 7 24 2 26 total (n,Xt) -7.24e-04 4.54e-04
1452 7 25 2 26 total (n,Xt) -3.01e-03 1.27e-03
1453 7 26 2 26 total (n,Xt) -5.95e-04 2.97e-04
1454 7 27 2 26 total (n,Xt) -1.93e-03 8.04e-04
1455 7 28 2 26 total (n,Xt) -1.79e-02 1.31e-02
Steps to Reproduce
- n,Xt score
- CylindricalMeshFilter tally with offset mesh origin
