MSRE controlrods end up with an offset bounding region #92

Closed ebknudsen closed 4 months ago

ebknudsen commented 5 months ago

When importing the MSRE control rods, OpenMC reports a bounding box which is not centered on the rod. msre_control_rod_noic_0 1_0 5_xy, which: a) complicates placement of the rod b) becomes problematic if coupled with impilcit complement set to anything but void.

We suspect this is caused by the faceting tolerance tag. This is attached to an additional dummy vertex at (0,0,0) which is likely what causes the problem.
