Will two many repeate numbers (in cubicArray) stuck the simulation process?

[JianbingDong]

I am simulating a CT scanner system. after constructing my CTScanner geometry as the Gate user's guide, I set the pixel size to 0.1 0.1 0. mm for XYZ axes, respectively, and the CTScanner module size is 23. cm, 19. cm, 1. mm. So my projection data should have 2300 pixels in X axis, and 1900 pixels for Y axis. So I use cubicArray repeater to construct the whole Scanner. Here is how i repeated the pixels. `/gate/pixel/repeaters/insert cubicArray

/gate/pixel/cubicArray/setRepeatNumberX 1500

/gate/pixel/cubicArray/setRepeatNumberY 950

/gate/pixel/cubicArray/setRepeatNumberZ 1

/gate/pixel/cubicArray/setRepeatVector 0.1 0.1 0. mm

/gate/pixel/cubicArray/autoCenter true`

When I start the Gate, it stucked in [Core-0] Initialization of geometry for many hours, and nothing happend.

Of course, if the repeatNumberX and repeatNumberY is small, like 100 and 100, the simulation will correctly finished. So I was wandering will too big repeatNumber will stuck the simulation? or is there anything I can do to fix this problem?
