When "sort_enclosure": true is selected the enclosure cell(s) is repeated twice in the MCNP input file, using the same cell numbering. If one copy of the cell(s) is manually cancelled from the MCNP input, the geometry still presents errors that are not present when "sort_enclosure": false is set. The geometry errors are due to a wrong sense of some of the surfaces used in the cell description of the enclosure.
Enclosure is written in cell #4 of the attached examples and should be defined as follows:
4 0 -3 4 8 11 -12 -5 (15:14:-13)
It is instead defines as follows when "sort_enclosure": true:
C ##########################################################
C ENCLOSURE 1
C ##########################################################
C
4 0 3 4 8 11 12 -5 (15:14:-13)
