2D3D method, 3DC5G7 model, cannot converge

[YINGCHIYV]

According to parameter Settings on page 91 of paper " Orthogonal-Mesh, 3-D Sn with Embedded 2-D Method of Characteristics for Whole-Core, Pin-Resolved Reactor Analysis ", the input card uses TW CDD-DDFF method to calculate the 3DC5G7 model set by itself.
The Fission source convergence curve does not agree with the fission source convergence curve in the paper.
The operation result of the 2DC5G7 model is correct, but the 3DC5G7 model cannot operate normally, and there is no example of the 3DC5G7 input card for reference. I have no clue about this. Could you please provide an example of the geometric setting of the 3DC5G7 model and the input card of the TW CDD-DDFF method?
